IR ThunderGun Impact Wrenches any opinions?

Air Cat's aren't bad but not as solid and long lasting as the IR guns. The Air Cat rating of 1000 ft. lb. is "nut busting torque". The latest jargon is "breakaway torque" Tighten a nut and bolt up to 1000 ft/lb. and if it will take it loose it has 1000 ft/lb of "nut busting torque". The IR guns are tested on a industry standard torque meter at 90 psi. for 10 seconds. I have seen a few of the newest impacts rated @ 100 psi. but the numbers should be close to the same. tmm
