Experiences buying used cartridges

Well I am that Guy that bought a EPC -100 Technics cart from Greg / Victor or whatever his name is this week at GRG. Here is how this guy works. First off, if you have a problem he pulls the stall tactic until you are past the point of a pay pal refund and feedback on this site. (so if you have a problem with GRG right now, you better dispute your pay-pal ASAP) Then he does the old I did not get your emails, I sorry I was in Russia at the Olympics. Then he says, send it back and I will have it repaired. Then he never answers your emails ever again. He has your money and his defective cart back, then he then resells again to some other poor schmuck. I actually saw the cart I sent back to him advertised with the same serial number 2 weeks later. Meanwhile he answers all of my kids emails about other carts while he is supposed to be in Russia. When I finally did get him on the phone he threatened to have someone to pay me a visit to give me a beating. So I jumped on A-gone and posted questions to all of his adds saying stay away, he burnt me for $500. All he did was block me. Stay away from this guy unless your in driving distance to give him a personal refund, if you catch my drift.
I have had him banned from Canuck Audio Mart and US Audio Mart. He would not even make contact with the moderators over this dispute.
His tactics prevent users from getting their money back and leaving negative feedback.
He also goes under the handle ViraUSA
GRG Audio are thieves, run for the hills and never look back.
