It was not cheap at $169 CDN, plus another $21 for the optional rain cover, but now that I've been using if for a few months I think it's worth the extra dough. The hook system makes all the difference - it's a breeze to get it on and off the rack. It has the built-in laptop pouch which is suspended and I can carry a crapload of stuff in the bag. I love it.
