Autopen Autographs now openly sold on ebay
 

the following sellers are now openly selling autopen autographs on ebay -
sports_buff
presidentialcollectibles (look at his closed auctions)

The story that is offered by presidential is that the autopen machine is in China and that you send them the pen, the autograph sample and the medium you want signed.
The term "Made In China" now takes on new meaning :(
Supposedly this machine is a new and improved model which makes the signature virtually indistinguishable from the real thing.

Would someone be able to tell looking at it in person?

There are tells with autopens but allegedly these are being penned with a new improved machine.
