Has anybody used the Rick Steves convertible carry-on / "Back door bag"? I'm looking for a new backpack for a Thailand trip, and I was thinking of this one. It is only $99, and it matches the maximum allowable dimensions for most airlines carry-on allowance. It doesn't look particularly functional as a back pack though, so I was wondering if anybody here has tried it.

I'm also looking at the dana design Far Flung bag.

Any other suggestions for a back that is nice, relatively light, and able to be taken carry-on?
