If that's on a site you'll be selling things on in the future, I'd make a thread about it there. The forums I'm on for my Stealth have a "Buyer/Seller Review" subforum in the for sale section, and a feedback system for transactions made through the board. It sounds like you were likely in the right, but I would want to clear the air at least on the SRT forum you sold it on.
You know how quick people are even on here to say "he's banned on this other board" or "I think he's scammed a couple people" over stupid shit, probably similar to this....
Just my opinion.
