Chris,
Lets see if I can stir up this hornets nest again (done this once before long ago). As an alternative to a new cheap, low quality BC, why not look into a good quality used BC? Now, I am not suggesting that you get a worn out rental but there are good deals to be had on little used, quality gear. Quality scuba equipment will last many years if taken care of...my old BC is a mid 80's vintage and except for some cosmetic damage, still in safe diveable condition and to be honest, the only real reason I replaced it was I just wanted a new one.. There are people who get into scuba, buy a lot of gear and then get out for whatever reason, this gear can be a great deal. Last summer I purchased a Scubapro reg, Genesis comp, an Oceanic BC and a bunch of other sruff for $700, per the computer, the gear had 3 dives on it. I only wanted the reg and I have since sold the stuff I did not want and ended up with about $200 in the reg/comp. I would highly suggest that if you do look at used gear, have it checked/serviced by a shop before you use it or better yet, before you buy it. A final suggestion is to check around the dive shops and look for deals on "last years models", sometimes shops have a earlier model that they will really deal on.
