@danj I have found the more desirable 13" 2012 for less on eBay then that one. They average in the $230-350 range if you look around.
Granted you are taking a chance on these machines in the sense they have issues with things like the hard drive cable (failure prone; patch and replace the cable if you have performance issues) and ignored maintenance like the thermal paste, high mileage batteries and worse then expected cosmetics but eBay has a solid return policy if you get a bum that can’t be saved.
I got my 2011 to replace a dead end Merom A1181 for sub $200 over cosmetics. The worst I found on it is 2 barely visible dents I would probably need to point out to someone unaware and a few scratches on the LCD assembly. I don’t care about a few blemishes at that price point since it’s ~6 generations newer.
