Given the other thead... I thought I would post up my expirences that are fairly recent.
Paul has been a pretty well known and active member here for as long as I have, so I felt confident going into these transactions. I wouldn't have had the same feeling about just anyone.
Sold a MHI EVO III 16G turbo with blown oil seal to Paul. Since he's in China, it was shipped to his U.S. shop (darren@ffwdconnection) that was putting things together for him. It was a flawless transaction, and he had great communication the whole time.
Even more recently, I sold him a brand new Centerforce Dual Friction clutch. This he wanted me to ship to China. I was VERY nervous about this, but again, because he's a active and long standing member here, I felt it was worth it to help him out. He paid for the $61 in shipping (if I remember correctly), no questions asked, and it made it fine. Again, great communication during the whole process.
I wouldn't hesitate to deal with him anytime.
