Cheers for all your replies.

I want one for light use, really for maintaining & servicing my car.
The Clarke corded gun is the one I noticed on eBay and I took a liking too lol.

First job I want it for is undoing the bolts holding the lower suspension arms on, with restricted access to the nuts, using an impact wrench on the bolts seems like the easier option. Unless anyone knows of an easier way.
