I'm thinking about buying a cordless impact gun. I was wondering if anyone on here has one, what brand, good/bad, etc. How much torque do I need? The prices are all over the place, with Sears Craftsman starting around $80 and the Milwaukee's up to over $400.

The tool will be used to assemble my front suspension (for starters). So it will need to be powerful enough and small enough to fit in some tight places (torquing the UCA's comes to mind).

Thank you in advance!
