Most places only sell the import stuff anymore. Even Campbell H is import now, and what Sears sells. I think even Walmart has those and good selection of air tools where I'm at. I have a local HDC or Homier's Import place, they have same brands as Harb FR, just cheaper yet! I have no problem with the $25 ones, when they go bad, ditch it and buy another. It takes quite awhile for that to happen. ONe problem with 1/2" impact of mine is it doesn't always loosen things I CAN get loose with a breaker bar. It works stronger to tighten bolts though. I use it mostly for speed and convenience when dissassembling items.
If your a too Nut, pay $200 or more and get the ONE that Last's a liftime! Sure!
