ZR65mc that much better than ZR60??

I was going to go ahead and pick up a ZR60 on eBay this week, as they can be had for $250-260 all day long. Then I saw this:

Is the ZR65mc worth the extra $40-50? What does "Refurbished by Canon USA" mean exactly? Is that a warning sign to stay away from this camcorder?

Thanks for the help.
