I've had an old Aire Lynx II inflatable for the past 10 years or so and love the stability and durability of these boats. Mine is a self bailing whitewater version that's great on moving water but absolutely sucks on lakes as it has no skegs or keel line of any kind.
Boatstogo.com sells very high quality inflatables at about half the cost of an Aire. I think I'm going to sell my Aire and buy one of these. Been eyeing them for a while and they keep getting better.
