which impact wrench

I'd look for a used IR 231 at a pawn shop.

I've seen them for as little as $30.

It's the "industry standard", so there are LOTS of them floating around.

My wife has a very small compressor that she used to run a nail gun with.
110v and light enough for a 100# woman to carry around.

It runs my 232 (the big brother to the 231) just fine. At least long enough to do a wheel's worth of lugs before it needs to charge up.

Funny, what that compressor won't do, is run my cheap, HF 3/8 air ratchet.

If you do get anything air or electric powered from a pawn shop, have then demo it for you. They should have several compressors, so ask to use one similar to yours.
