hummm,,some unreported cash maybe.

Maybe a different currency because he's from another country????

Rik jhas always been able to get me whatever, whenever I need and pricing always in line

There is a guy that I've been working with on some Arneson parts that I have. He sent Rik a deposit on some ASD-7s, and Rik has since disappeared. No refund, no return call, nothing. Basically took his money and ran. The last he talked to him, he was told they moved to a new foundry and parts would be coming soon. That was many, many months ago. Anyone reading this, should be smart and not send Rik money. If you really want to go Arneson drives, go through twin disk for ASD-8s, and get the drop boxes from SCS. Both very reputable companies and you will get the parts you order and pay for.
