Using scubadotcom, my choices would be (in order of preference):
1. Dive Rite - great regs, excellent custmer service, great prices
2. Zeagle - as close to the Apeks line as you will get without paying extra for the branding, great quality, good pricing, good service
3. Poseidon - the only reason I list this last is the price, these are great regs built to last a lifetime or two.

I started out with a Sherwood Maximus, good reg, breathed ok, but that dry bleed thing they have going on is just not for me.
