Wrong! They are quickly FIXED, and the fix is promulgated to the entire customer base - sometimes even at BVM's expense. Yes, BVM jets are expensive, but if they have the kind of jet you want and you can afford it, you will not regret the purchase. If you want something that BVM doesn't offer, or can't afford a BVM kit, there are plenty of other viable alternatives, but I would be willing to bet that you will not find many, if any, people who have actually bought and built a BVM kit that will complain that they paid too much...
