SB has almost completely influenced all my purchases.
Regulators, computer, and other small stuff purchased from Scubatoys and other dealers recommended by others after researching on SB.
I knew very little about scuba gear before I found SB. There is a lot of brand loyalty among some here, and brand hatred as well. If you look at the information, research the posts, and filter out some of the bs that is included, there is a wealth of information on the board. Lots of experienced divers that have tried almost every type of equipment available, and most will give you a honest opinion of their experiences with that equipment. A lot of it comes down to personal preference. But when you live in a small town like I do, and have only 1 small LDS that carries only Scubapro stuff and pushes it hard, this is the only place to ask questions and get honest answers about other brands. Without ScubaBoard, I would not have my beloved Apeks ATX200 reg, my DSS BP/W (which I can't imagine diving without), my Bare 7mm SGS wetsuit from DiveTank, the VersaPro computer I bought from ScubaToys, or a long list of small stuff that I got from information gathered here as well. Oh, and I would not be going to Valhalla in November with Surface Interval Scuba without SB either!
