have an 1150, trigger control takes some getting used to but its an excellent impact gun. Five of us at my work have them and I haven't heard anyone complain about them.
I've got a 16" 8 lb Wilton sledge which I use for wheel bearings, rotors etc. The hammer is an absolute Monster. and from the Wilton website: "Technology that for 2 full years after purchase, break the handle under normal wear and tear and receive $1,000."
