Recommend a impact gun (battery)

[daddyfixit]

rechargeable snap on 1/2" drive would be first choice, expensive but does the job without falling to bits, and has the advantage of not being tied to an airline ? I have GIVEN 1/2" drive airguns to people to use and they are still in their boxes unused --as they preferred the snap-on ones !
I also won a 3/8" drive impact gun/drill/torch set in a magazine competition; great for getting in tight places, but wont undo wheel nuts----but great for re-assembling due to being so compact.
when things are gorilla-tight, the red snap-on 1/2" airgun gets used....never fails.
