Advice on buying a used Warn winch

Hi guys, just looking for some advice on buying a used winch. I've never owned a winch before, anything I should look for or test when buying other than connecting it up to a battery and making sure it works? 2 on the local classifieds have caught my eye, a Warn CE XD9000 ($500) and a Warn 8274
