It's not ideal, being a case for a 15.4 laptop, but I got two for only $2 each. It's a Office Depot brand, Foray, and has tons of pockets, a luggage handle passthru, a shoulder strap and a padded laptop compartment. It even has a big pocket for files with built-in dividers and a organizor for PDA, cell phones, etc.

These were on the Clearance aisle and all 3 were Royal Blue. I don't know if they come in other colors. But, for only $2! I got 2 bags just because they were sooo cheap.

And, yes, that's two dollars each. So I paid four bucks plus tax.

You can see it on officedepot.com, search for Foray 567726. It's $49.99 there. Sorry, I don't know how to copy addresses on my eDGe.
