I've got a cheap Chinese made electric impact driver that I bought 5 years ago for $39. It gets a couple of months of heavy use every year. No problems. Totally worth it. I use it when I'm somewhere that has ready access to power, but limited/no air supply. If it ever dies I might be tempted to replace it with a decent Dewalt or Porter-Cable, but 5 years for $40 is hard to beat.
