Reg, you can get a good but simple ScubaPro Mk2+ for about $250, but you will need a pressure gauge, and depth meter ~200, you may want a much nicer reg that does well in very cold waters ( Im not sure how cold the water is up there) then you looking at around 4-600 for the reg and you will still need an SPG (submersible pressure gauge).
Buoyancy Device price really varies, I would recommend a back plate and wings. You can get a top notch set up for $700, or you can buy cheaper and possibly upgrade later and spend more
Drysuit you looking probably around 1500 on up. I dive a DUI TLS350 signature with zip seals. (replaceable neck and wrist seals, actually just saved me a day of diving yesterday when I ripped a neck seal)
Mask 20-125 all about fit here, but I like the ScubaPro Frameless $125, Atomics 100 and halcyon 60. Again all about fit, but you want a nice low volume mask, so its quicker and easier to clear
fins 80-250 Top end Apollo Bio Fin spilt fins with stainless steel spring straps 250; super floppy piece of rubber that can swim really fast with little effort, most split fins are ~175 or so, you can get some cheapy old fashioned fins that are cheap and will kill your calf muscles, I recommend ScubaPro Jets or OMS slip streams (think old frogman style) ~100 OMS are the same as the Jets but different material and weigh about half of the originals. Blades you cant swim as fast, but you have more fine control for positioning, more feed back, and you can learn more efficient kicks like the frog kick and cool fun kicks like the helicopter turn and back kick (yes it is possible to swim backwards without using your hands)
lets see what else do I take diving:gloves 30-50 unless you go with drygloves, if in a wetsuit, booties ~30-100, hood 50 (dry suit comes with booties and a hood), drysuit undergarments 100-500 drysuit keeps you dry, not warm. knife 30-100 please don't buy a big *** Rambo knife and strap it to the outside of your leg..... flash light 30-2000, this can vary from a small flash light you stick in your pocket for looking under rocks to a big 18w HID (read metal halide) light head attached to your hand with an umbilical leading to a large battery pack that is strapped to your waist belt (expensive but ohhh so worth it), if you HAVE to a snorkel $the ceaper the better! Dont waste your money on a Super Sahara Dry 5000 with ping ball check valve (honestly they make them) they are expensive, top heavy, and POS just get a plane jane snorkel with a piece of corigated flexible tubing so it is somewhat adjustable to fit in your mouth. If you want to splurge, you can get a snorkel that rolls up, so you can stash it in your pocket instead of having it bounce around on your mask, or better yet take up less space in your dive bag when you leave it there.
When you start diving, you will need your personal gear, mask, fins, snorkel, gloves, booties. (maybe hood) and the rest should be offered as part of the class. Do some dives and rent different types of gear, or talk to people and borrow theirs for a while. I did some research before I bought all my gear, I have replace a few pieces, I will list what and why
mask: fit on dry land, fit in pool, leaked like a sieve in the ocean. was a cheapy Aqua Lung mask replaced with ScubaMax frameless (knock off ScubaPro frameless at fraction of the price), then replaced that when mother nature stole it from me on a rough beach exit....
fins: started with atomics split fins, fine for normal recreational diving, got drysuit (wear size 15-16 shoes) and fins wouldn't fit, bought turtles (like above jets but bigger) lost one fin in another rough beach exit, bought another pair, then bough OMS slipstreams. really happy with these. (not to sound like a salesman but whatever fins you buy, invest in a pair of spring straps! they dont dry rot and crack, are instantly adjustable, they're great!)
BC bought a Dive Rite backplate with Rec wing: wasn't happy with "delux" harness so replaced with simple, single piece of 2" webbing. Took some getting used to getting in and out but much happier now$20. Started diving in double steel tanks, and tired of swapping gear back and forth from sing to doubles, also found that Rec wing was just big enough for doubles but it was designed for single tank OR double tank and does neither that well, decided to get a wing dedicated to doubles wings. I bought a Deep Sea Supply back plate and wings. ~500 found wing would float my gear and mfg wouldnt allow a return or exchange, sold the wing and bought a Halcyon wing, love it! Did another couple of dives with Rec wing with single tank and sold the wing to buy a smaller Halcyon single wing, love it too.
wetsuit: JMJ custom wetsuit, for a wet suit...love it. upgraded to a dui drysuit, love it more!
flash light: Underwater Kinetics SL4 $30, nice flash light, upgraded (?) to a halcyon scout $100 added a Halcyon 18w HID $$$ cost more than some of my cars but sooooo worth it.
Regulators: first, inexpesnive used Sherwood Brut complete reg set $200, free flowed like a fiend in pool, shop that said it was rebuilt, admitted that were not rebuilt... didnt trust it so bought Scuba Pro Mk25/S600 $600. High dollar reg, very nice. Got into doubles and wanted simple and reliable environmentally sealed (for cold and nasty water) regs so bought Apeks DS4 for doubles, then got into decompression bottles and bought more Apeks, just decided I wanted all my regs the same for spare parts... just traded my SP for Apeks in some ways I think the SP may be a slightly better reg(I am/was a reg tech so I have my own oppinion on regs based on inside workings...), but happy with the apeks.
