I second the Luggage Works $80 bag. Had mine for almost 6 years now and it's still going strong. I couldn't imagine getting much more utility out of a $300 Coyote Works or any other bag. For the record, I am NOT a commuter (yet) so your mileage may vary if you travel with your flight case.

And I've been hearing EFBs since I got hired almost 6 years ago :P
