I also recommend the Costco Kirkland luggage. My parents have a 26" that is well put together. Costco seems to update the luggage when new technology adds functionality to bags. They upgraded the hardware and added bigger feet and a base handle for the latest 22". I'm going to get a 22" for myself when I finally beat my tired midrange Atlantic to death--I'm not that thrilled with it.

You certainly can't beat the price and you can't beat the warranty. From what I've read, bring a busted one into Costco and walk out with a brandspanking new one. No ridiculous handling fees that almost equal the cost of a new bag to fix and old one.
