well there is a local 2nd hand gear store where i live and it has timbuk2s all the time for like $20-30, so suck comes to mind... I'm down with the older chromes but the new ones just dont seem the same... this is my bag
http://www.pacdesigns.com/oversize.htm costs a mint and a half but its the most comfortable messenger bag... I rode across the country with this on my back pretty well loaded up so if thats not comfort I dont know what is. Also hauled 2 full road bikes with wheels strapped into/onto it.
