This is an old tread, but I'm sure it's a repeating request.
I've purchased 1/4, 3/8, and 1/2 CDI torque wrenches from Ebay. These are the same as SnapOn (i.e., CDI makes SnapOn wrenches). This has covered all my needs, from torquing the seat bolt on my carbon-frame bicycle to some reasonably stout suspension bolts. All three wrenches looked to be new - and I mean not a scratch on them, and they all had the calibration paperwork and plastic cases. I didn't pay more than $50 for any one of them, and am extremely happy with them all - they're great wrenches and noticeably better than what they replaced.
Ebay's great for quality tools if you have time. It took me a few tries to get these at rock-bottom prices.
