Audio Magic: Buyer of used Mini Digitals beware

Since I am downsizing my Audio Magic power conditioning rig, I am looking for a used Audio Magic Mini Digital. Jerry, in the beginning, didn't have faceplates that said Digital Mini-- they just said Stealth Mini Purifier. I had one, but purchased it directly from Jerry, Mr. Silver himself, of Audio Magic, who assured me what the deal was. I found out, almost the hard way (before hitting send on the Paypal website ok a little exageration) that an Audiogoner is selling one as a Digital and it turns out doesn't have any idea if it is or isn't. There are a lot of AM digitals on the 'gon, but looking at it now? How is one to know for sure? Bottom line? Check their feedback, and pray. They could have been just as easily misled as I was.
