Sometimes you get what you pay for. Sometimes not. I've heard good things, from "thrifty" pilots about the travel bags from Costco. When my Travelpro crapped to bed after only 16 years, I went on-line and did my shopping. I settled on a Swiss Army rollaboard. It's lightweight, expandable, very good looking (it needs to be in order to keep up with me), and its handle swivels so that you can pull it along with your hand vertical, instead of horizontal (which is not so great, ergonomically speaking.) About two years into owning it, one of the bolts that holds the handle onto the case managed to unscrew and got lost somewhere in the internals of the bag. I called the company and in 2 days had two new screws and their associated nuts, along with directions to get into the bags internals, delivered, for free of course. Here's a link to one place that sells them.
