Prop I'm Very Sorry to hear that You've had Problems with Jason, but I'm glad You got a refund.
As information I've brought dozens of Tamiya KT parts from him off eBay in the last year INCLUDING some just this past week. I got the parts Within a week with NO problems and PAID Through Paypal so his Paypal Account wasn't suspended a week ago.
I dunno what's going on with Your case though. Very, Very Odd.
