[Superman]

I am as thrifty as anyone here and have gotten good use out of a wide variety of inexpensive tools, but here is where you want to get something good, like IR. Used, pawn shop, whatever. The difference between a good impact wrench and a poor one is like night and day. A good one will save you HOURS of frustration and work compared to a mediocre one. It's a choice between frustration and bliss.
