I've recently purchased some Paul Smith luggage - the larger version of this infact:

If that's advertising, then the mods can delete it.
Yeah OK it aint cheap (£395 for the size I had), but I'm amazed at how strong and sturdy it is. It survived its first few flights/trips without any problem. Whether it will stand the test of time is another matter.
Prior to this I had a Trunk & Co case. Lasted pretty well, around 8 years with plenty of travelling in those 8 years. That was until Baggage handlers in Brisbane got their hands on it during my Ashes trip last December. Snapped not one, but both of the straps
and broke the zip!
A mate of mine has Tumi, can't rate it highly enough.
