Well, following that logic, one could buy a BCD that's less than 200 dollars. I know, as I did that back in the day... The problem is, I'm not changing what I'm saying, I've been consistent.Again, you are changing the discussion. The question was: what would you buy for a 14 year old? And I answered with what I did in fact buy my 14 year old. And it's still what I would buy for a 14 year old today -- I would save money for other equipment and dive trips, and not spend hundreds more just on the off chance he wants to do technical diving at some point in his life.
For a hobby/industry that struggles to attract new people (as discussed on many threads here) perhaps the message that a $230 BCD works just fine for recreational diving is something that should not always be met with ire that people should spend more than twice as much for modularity that most never need.
Cheapest isn't best - there's more than one person here that knows that reselling a bp/w is far more "profitable" than reselling a bcd. You can go do a deep dive on craigslist to see how many people who were poorly trained and suckered into buying jacket bcds are looking to offload them. Then come here and see what the average purchase price of of a used BP/W is and tell all of us how you have a better solution.
I will grant you that if you assume that the diver isn't going to like diving you can save money by buying cheap, but what's the point in that?
And to put my point on the line, OP, if your son doesn't take to diving, I'll do a free class with him and I'll bet you that I can change his mind... I didn't get in this business to make money, and I don't like suckering people into bad decisions, and the BCD is always a bad decision.
