I usualy buy from SEARS APPLIANCE OUTLET. They have dings/marks, but at upto 50% off (or 70% off if you believe their ad) on good brands. These are quality rejects, returns, or shipping damage goods. We have some rental properties, and got tired of craigslist's junks. Sears have warranties.

Dont go through their online outlet, go to their physical outlet location. AND if you go a month or so after a holiday/nationwide sale, you'll have many more choices.

No issues on the mechanicals.

Good Luck!
