The L.L. Bean adventure duffels are a good option. I think you could get away with taking one of the medium sized ones on board the plane as a carry on even though, technically, they're a little too big. They're well built and the price is right. The only problem I ran into is that the medium size bag is only 23" long. That's about an inch too short for my fins. I could fit most of my other gear with no problem: 3mm wetsuit (rolled), light weight mesh gear bag, booties, gloves, full size regs and computer, and my backplate and cam bands (w/o the wing). I found that the wheeled bag doesn't stretch as much as the regular bag because of the collapsible handle and other hardware, so it might not hold as much. Still these bags are a good option.
