My laptop bag's handle just broke. I'm looking for something along the same line as the Timbuk2 Laptop Messenger bag. It must have a padded laptop compartment, padded handle and waterproof. Other than that, I'm fairly open. I'll be carrying an IBM thinkpad T-series 14" and 1 or 2 big books. Any recommendations? Oh, under 100 bucks would be great. Thanks.
