I bought a Seekonk TSQ-150 used on eBay very cheap, I'm going to calibrate it with a weight but I can send it back for calibration too.
It has a 3/8" drive which is weird for an inch-lb wrench but I got a couple adapters from McMaster Carr for standard 1/4" screw driver bits and many places including McMaster Carr sell extended length bits in flat, hex, torx and more.
For high quality on a budget, it's hard to do better.
