Keep in mind, one can only have a chance of "discontent" or "regret" (not saying they will) if they have a chance to evaluate different options. Given that opportunity, they may or may not come to that feeling. When presented with a biased answer to questions (and that bias going either way), it is in no way easy to have a independent evaluation. Even if the equipment may be available, if it is not in favor with the seller, chances are, it will not be set up properly for the individual to have the best opportunity to see it in the best light. I have to actually cross an international border to actually see a BP/W in a shop that I consider "local". The ones here do not carry them....its not in their "program". Years back when I got my back-inflate, it was never set up for me, and in fact, I hated it from day one, but needed it rather than my BC because of diving a dry suit. I learned on my own that things were not correct. I also learned there were things I could never get right, hence the quest continued, and for me, a BP/W became the best option (again, for ME).
