I have 2 torque wrenches....one 1/4" drive that is in inch pounds and one 1/2 drive that is in ft.lbs. Then I have a set of adapters that I convert to 1/4, 3/8, or 1/2, as needed. I bought everything at Harbor Freight. If you catch the wrenches on sale, you can pick them up for between $12 and $25. The 1/4 one will be the more expensive one, ironically.
