You can absolutely never go wrong with a piece of SCUBAPRO equipment!! (As long as it's suited for the type of diving you'll be doing). Do it - you'll be happy with your purchase.
I use a SCUBAPRO Classic Plus, which, though a bit more expensive, I think is the best BCD you can get for recreational diving! It's comfortable, simple, and operates without a flaw. Several people I know use the Knighthawk, and they say the same thing - it's great! I myself have rented them a couple of times, and I tend to agree - though I prefer a BCD without adjustable shoulder-straps.
