All our crew cases were Samsonite, still are. I had one that was in constant use 5 days out of 9 for 11 years. when I handed it back it still worked including the locks, catches and wheels like it was new. For 4 wheelers look at American Tourister bags which are made by Samsonite. My wife has a couple, small and large and they are great value and last better than other brands. The plus side to Samsonite is the warranty and parts availability.
For my diving and walkabout trips I use a North Face duffle size Large which when needed can either go in the hold or be squashed down and fit the overheads.
