Bought a "Good Condition" Angel G7 from him. Shipped very quickly, easy to get a hold of. Overall, good.
Now, that's not all of it... the Angel I got came in bad condition, was leaking a lot, and the breech was jammed. It required much work on my part to get this all fixed, especially since this was my first Angel marker. Then when I asked him about it, he said it was USPS's fault, and they must have dropped it... So I guess dropping a well packaged box messes up internal o-rings and the breech
Another thing, my payment was slightly delayed, which is my fault, because he said he would get "Tracking" on his shipment, but he got confirmation instead, and upon reviewing the confirmation, and calling USPS, there was no way to verify that it was ever shipped, or where it was going. I have had problems in the past where people have created false slips. The problem with this was, that my dad wanted to call him first, then paypal to him, which delayed it a bit. But Shep called my house 4 times in a span of a few hours. He's very impatient...
Shep's feedback seems spotless besides this... so dealing with him is soley up to you. Maybe all of his other transactions went well, but I know mine was disasterous... So, good luck to all
