I would say that you would be hard-pressed to find a really great durable messenger bag for cheap. I am going to have to go with Seagull Bags. I got one for Christmas after trying a Timbuk 2 and Chrome. The Chrome was surely durable feeling and comfy, and the Timbuk 2 less so on both fronts. The Seagull cost me less (Black bag) than a Chrome and has a PERFECT design. I also feel it looks loads better than Chromes and is devoid of logos except for a tag on the front buckle. The thing is also EXTREMELY durable and have ran it under water to test it's weather resistance, which is unbelievable. I highly recommend them. Also, the staff is nice and small and REALLY responsive. I sent an email about how much I enjoyed the bag and they got back to me in a mere three hours. Awesome service.
