Over the winter I bought a nice DeWalt cordless impact wrench, but it just doesn't have enough torque. I often find myself either taking much, much longer on a project or like today getting stuck and simply not being able to move forward since the tool I have can't handle it. It's become very frustrating!

I'm looking for suggestions on an impact gun under $250 (the lower the better of course, but do want it to be a good / reliable unit). I've seen several of the Ingersoll Rand/IR 2135TI guns over on eBay for fairly decent prices. According to it's specs, it has a max. torque of 1,000 ft.-lbs and weighs under 4 lbs. It also has four power settings so I don't start snapping bolts off.

Thoughts, suggestions?
