I highly recommend my Deuter Futura. Its probably quite a bit pricier than you're looking to pay but its worth every penny. It has a mesh frame which keeps the bag off your back and places the weight directly behind your belly button which is exactly where it belongs. My bag has survived a year of bike commuting without a scratch while hauling a MBP and a change of clothes.
