I needed a new 1/2" impact gun for work, 'cause the 6.5lb CP733 my employer gave me was killing my wrist. After hearing good reviews here about the Ingersoll-Rand 2135TI and checking it out in person at Sears, I asked for it for Christmas, and Santa (OK, my mom & stepdad) delivered. I have 3 words to describe it: THIS THING ROCKS!! Today I removed two 2" long, 15/16" full-thread bolts that had red Loctite on them (they hold the front countershafts in place in a Fuller Roadranger transmission). With the CP gun, I would have had to get the torch to heat 'em up after failing on the first try, but the IR zipped them out like they were wrench-snug, not torqued and Loctited. If you need a good impact gun for serious home wrenching or professional use, look no further. It isn't a cheap tool, but the really good ones seldom are.
