After forever waiting, (3) Data Proof scanners hit eBay not long ago, a couple 160s and a 320, so I bought the 320. Received it yesterday only to find all the cards/relays were gone and rear terminal wiring just cut! Seller was very understanding and quickly offered a return, I am confident they were not being deceitful, just pushing used gear fast by non-technical people.
But anyhow, if it ends up on eBay again, don't want anyone else to run into the same issue, SN=353.
