Ads with "Checkup"

Pushes the bounds of believability IMHO. Goes great with memorable lines such as "box opened to inspect contents only" or "selling for a friend".

i dont buy it for 1 second,i emailed 1 constant seller & asked why all his ads say just back from audio classics & i got the speech about making sure the gear was up to mcintosh factory specs but at the same time the items come with no guarantee,smells like hype to me.

I hear ya!
I've been looking at some vintage tuners over at ebay and many of the ads state that the unit has been checked by a technician, cleaned and all buttons and switches lubed.
Gives me the feeling that I'm the one who is being lubed.

I would feel more comfortable buying a used piece that came back from the factory after a check up than from the seller with out a check up. I suspect the reason for the check up was due to a repair, but I would think that the manufacturer would want to do their best to send the product back in the best shape possible. Regardless of the reason for the visit, I would have more confidence in a used product because of the visit. Of course documentation and confirmation may be in order.
