You will probably want to start with an Aquamaster of some sort. I would look for a DA Aquamaster. They are constantly popping up on ebay, and generally run about $100 when the bidding dust settles. Eventually, you'll be able to get a Phoenix nozzle for it, and it will perform like any nice modern regulator. My current collection are DAs and a pair of Healthways single stage regs. I've rebuilt 3 of the 4, and they all breathe nicely now. It's mostly a comfort thing. Be prepared to spend some quality time in the pool, getting to know the gear. A Royal Aquamaster is also pretty easy to find. Both VDH and VSS currently have several regs for sale. If money is not a problem, I would start off buying one of theirs. You'll get a good reg rebuilt and tuned by an expert.
