I have used one of these for a couple of years and found it to be all I could want for bike work. It is sold under a variety of names and a WIDE variety of prices for the same tool. WIGGLE.COM has it listed as " X-Tools Essential Torque Wrench Set" for $39.43 total
Yep, I got the BikeHand version from Amazon for about $40. Maybe not 100% accurate, but close enough to avoid massively over-tightening something. And I don’t think super-accurate is needed for the stuff we’re tightening on bikes.
