I ain't spending over $150 on an impact
In this price range, a corded impact from any of the major brands. Milwaukee, dewalt, making, etc... Or go pneumatic but you will need a good air compressor with a decent sized tank.
Sorry I was literally walking out of the office on my last comment. If you want spend the money on any of the snap on, Matco etc... Varieties find me on here. I can get you a discount, that you more than likely wont get through a dealer, unless he is a friend.
Personally, my opinion, for what you are looking for, go corded.
