If you're willing to spend the money (once, and never again), Briggs and Riley is a very good option. Their products come with a lifetime guarantee, *including* airline damage. They have a wide range, and though their products aren't cheap, they are competitive at the high end of the market. I have the expandable roller, which comes with a garment bag and satisfies airline hand luggage size restrictions. It can expand to give an extra 3 inches of depth (great for fitting in all the Swiss chocolate...) The construction is sturdy, and it comes with all the extras that one would expect from the high end bags. Having used cheap luggage in the past, I can assure you that good quality luggage is worth its weight in gold: cheaper bags are okay for infrequent travellers, but they are not designed to do 100k miles.
