The LDS has new-old-stock (NOS) BCDs on 50% off. Most are discontinued models from Mares, SeacSub, ScubaPro. For example they Have the Mares Ariel which I'm guessing is at least 1-2 years old. Would these NOS units still be ok? What should I be looking for? My wife's BCD got busted last weekend (inflater hose tore off from the jacket) and would like to buy a one. We don't dive as often as we did and don't want to spend too much. Thanks.
