I bought some parts from him already and it went ok...
I sent him a money order with signature required to his PO box and according to the tracking it hasn't been picked up and was supposed to be returned...
He already shipped the parts to me...
I don't know if he picked up and signed for the money order or if it is on the way back to me...
However when dealing with new people that I don't know, I want a signature to prove that they got my money in case there are any disputes... Especially with a new guy on the forum with no history or feedback...
