I travel a lot, and have burned through three or four sets of luggage in the past seven years. The latest two suitcases are done...time to get two more (one for me, one for my husband). The carry-ons are still ok. I'm after a couple of medium-ish regular suitcases. I don't want a set right now because I never use all of the pieces, and really all I need is one carry-one and one medium-ish suitcase for slightly longer trips.

I'm not too concerned with 'style' or designer stuff when it comes to luggage, but I'd like the next suitcase to last a little bit longer - does anyone have any recommendations? I travel about 10-15 times a year or more. Most of the sets/cases I've bought over the past few years have been Samsonite and/or American Tourister. They last about two years maybe.

Is there something more durable?
