I've recently been in the market for one for school use, but im not really comfortable paying so much for a bag because of the name(ie timbuk2 and chrome). I'm looking for something preferably under $100. I've been checking out rickshaw zero messenger, but dislike that there aren't buckles. The SAG replicas on ebay seem alright, but are still pretty sketch. Wig bags seem pretty nice, but there doesn't seem to be any pricing info on them.

Are there any bags that you guys would recommend for school use? I need something on the larger side to hold textbooks and such, and maybe some camera gear for those times i go out to shoot.
