I've been dealing with this guy as well. Same rig. First he said bank transfer only, so I said Paypal only. He agreed then changed his mind, wanted moneygram. I said no way forget it. Then he said he would take paypal. My customer phoned paypal and explained the deal and they said they would cover the fraud risk, so we sent the payment. He then said thanks, he will ship when he "confirms payment", maybe a few days.
So I messaged him that he had 24 hours only to ship and send me tracking info, or I would begin a paypal dispute. He now says he will do that. I guess we'll see. If he is a scammer, he's not very smooth. Now I'm wondering if he is still trying to sell this rig. It should no longer be available. If he is still marketing it please PM me ASAP.
I bet Joann K. Salter is being scammed too. She probably accepts the money & most of it to the scammer & keeps a small amount for herself. Then when the stuff hits the fan, she will get in trouble & be responsible.
You can try to get a phone # for her & contact her.
