Rattle gun impact wrench - recommendation?

[M4cruiser]

After struggling with a strut removal, I think it may be time for me to invest in a rattle gun.

A quick Google shows loads available, how to choose?

Does anyone own one they are prepared to recommend, or to recommend to avoid!

Hello, thank you for the replies, yes I was assuming battery, or electric if I have to (not air though).
