Looking for a Laptop Backpack for XPS m1330

[x C0MMAND0 x]

I just ordered a Dell XPS m1330, and I am looking for a good backpack. I really want to get a backpack so I can have it strapped in there and also have some books and whatnot for school/work. Does anybody know any good backpacks for a 13.3" screen laptop? Ideally under $50.00, but for sure under $100.00.

EDIT
I'm looking at this backpack from amazon (http://www.amazon.com/Swiss-Gear-SA9768-Black-SwissGear/dp/B0019M7WEK/ref=sr_1_15?ie=UTF8&s=electronics&qid=1227573459&sr=1-15), because it looks as though it may fit my new laptop very nicely... Any thoughts?

Can't comment on 13" screens but the Targus range are very good if you can find the right size - my 9400 (17") goes everywhere in a Targus backpack, even on my push-bike.
