My Travelpro Plat4SE 24" suiter needs to be replaced. I started travelling a lot more a year or two back and stuff that counts as "normal wear and tear" like the wheel axles are going to give out soon and that's not covered by their "lifetime warranty".
I'd have gone with a Tumi Alpha in a heartbeat -- before Tumi changed their warranty. Now I think I'm going to go with a Briggs and Riley expandable 24" instead.
