Good idea! Talk to Larry on the phone and he will give you some great advice!
FWIW...I own a few different regs and BCs, as does my wife, and have been able to try some different regs and BC's.
I like the Dacor Viper, its a great reg for the price. I wouldn't use it for cold water.
My wife's Oceanic Zeta is incredible, easy, light, small, and reasonable. It is sealed, and good in cold or warm water. I fitted the second stage with a swivel. Ask Larry about it.
My Apeks ATX 200 rocks in all conditions, but its expensive, and I'm not aware of any place that you can get it online.
I dove the Zeagle Flathead ZX and Its just as good as the Apeks Expensive.
Check out the Zeagle Envoy deluxe. I played with one at my LDS and it looks great. Very reasonable price at Scubatoys.
BCD's...
Zeagle Ranger. (Love it! Kinda big to travel with. Expensive.)
Seaquest Balance(Very sleek and great to pack and travel. A little tricky control.)
Mares Z1000(Inexpensive, and I like it. Jacket style, but comfy and great control.)
Dacor Extremell(She loves it. Won't let me get her a Zeagle Zena.)
