$20 · Electric chain saw

This is about 10 years old and lightly used. It always worked exceptionally well. It has one small issue any handi-person ( ie; not me) can likely correct. The engineer who designed it clearly was not a Mensa candidate. The device for tightening the chain, saw a metal cog mated to a nylon cog. Yup, you guessed it, the nylon wore out fairly quick. The chain can still be tightened, you just have to do it more often with the current configuration.
