...I'm sure you'll have no trouble finding local reefers to help you spend your money. JP
Porter knows I'll help.
Check out the Deep Sea Aquatics 225, might be in your wheelhouse. Plenty of other quality tank manufacturers out there to choose from, including local builders.
If the tank is going to be backed up into a corner on the wall, a corner-overflow box will look the best in the tank but be more difficult to work on. A single overflow box in the center would give more access, but less visually appealing (in my opinion). Access vs. aesthetics. If you're keeping the front-to-back dimensions under 30", I'd go with a corner overflow.
Go with starphire glass if the budget allows. More scratch resistant than acrylic with the same (or at least, similar) optics. Acrylic is awesome if you have a unique design or starphire glass is way out of your budget. Having had both acrylic and low-iron glass, I'd pay up to a 50% premium for the low-iron glass. Everyone values these things differently though.
Skip the Berlin and Wet-dry. Having run multiple refugiums, I'd say run one only if you're a bit nocturnal and like to watch little critters run around at night when the rest of your tank is asleep. If you're running it only for nutrient export or pH balance, skip it and go with a better skimmer and more water changes for nutrient export and use a CO2 scrubber for pH. They're easier to maintain and less risk of Nitrates/Phoshates leaching back into the system. If you have room in the sump for a fuge and want to grow macro algae, use the chamber to tumble chaeto without sand or rock. That gives you plenty of access to vacuum out detritus if it forms and you don't have to move rock all over the place or worry about sand getting gunked up.
More than one way to be successful in this hobby. Go check out some local tanks and see what you like. Most importantly, think about what would go into maintaining the aspects of your design. The less you have to worry about maintenance, the more time you get to spend staring at or buying corals and fish.
