Potomac German Auto, in Frederick MD sells refurbished units. I talked to them yesterday and they said that they send out used ones to be refurbished. The difference in cost is about $300.

Used: $425
Refurbished: $750 or so

I'm not sure what to do, as I've already bought a used one and had it installed, only to learn that it was also bad. It has a warrenty, but I'm out the cost of labor from my mechanic. I'd hate to have another used one go bad on me and lose the installation cost again!

So I have to decide on a used or refurbished unit. What do you think?
