I use a North face duffle, that I got for 100 at the kadewe, like the Patagonia black hole but more solid, or this leather bag. My buddy had it made by a cordwainer, but didn't like the heavy gauge of leather. It's like a marine Alice pack.

As long as the bag can be used as a carry on and fit in your lap in a car, I think it's a good choice. The possibility of it being stolen, or making me a mark at a hotel, has made me suspicious of expensive luggage.
