IR ThunderGun Impact Wrenches any opinions?

Thanks for all the replies! I ended up ordering the thundergun 232-TGSL. Maybe after I get it I will take it over to my brothers house and compare to his beast of a gun and see if it really measures up or not. I am still kinda skeptical it can do the same torque of a bigger gun at half the price. If it does I am sure its not built as tough to deal with that abuse but I am just a hobbiest mechanic or whatever you wanna call it anyways. So for what I need this gun to do, it will probably last me forever if its the same quality as any other IR product.
