This cheap Ryobi 4 volt battery operated screwdriver has more than paid for itself in not only time to run up long machine screws but also wear and tear on my wrists and elbows.
It doesn't drive in wood screws but it does a fantastic job for what it was meant for.
The multi Milwaukee screwdriver is a good deal too for I think under ten bucks.
I think I paid seven something on sale.
I use it to tighten wire lugs and other things.
