I would get something like a Duncan, Frogspawn, Hammer or torch. They're all easy to keep as long as you keep your water stable and if you only have a few, you won't need to do any dosing. So all you have to worry about is water temp and SG. Yes continue to test all parameters but a few LPS isn't going to suck Alk and Ca out of your tank very quickly and water changes will take care of this for you.
My tank is heavily stocked and I'm using Instant Ocean Reef Crystals. I do a 10% WC weekly and my parameters stay very stable.
Here is a link to my tank.

I'll be adding a lot more pictures today as I've not added many in 2 months. I just had a big day at a swap meet this past Saturday and got a lot of new corals.

:dance:
So I also agree with NOT getting anything that can become a plague in your tank and take over all available rock surface :hammer: For this reason I don't keep zoas or palys, GSP, cloves etc.
