Well I got a new to me air compressor. Its a portercable compressor that belonged to my dad. All I have to do is replace the piston and sleeve and it will be brand new. Anyways, on to the point of the post. I want to get a 1/2" drive impact. I want to buy one that will last but wont break the bank. What has done yall right? Where should I look? How much can I expect to pay? Please give the specs of the impacts yall use as far as drive and forward/reverse tourqe ect. Thanks yall.
