I've emailed them, and they are helpful. But they appeared to drop off ebay for a week or two, and I haven't checked in. Sounds good, but for about $700 I can get a C6 from TCI, at Summit in Reno. I figure that way I'm sure what I'm getting. When it comes to turning loose a lot of money, I'm nervous about someone a continent away.

But like I said, they responded promptly to an email and, even though I couldn't find them for a few days in February on eBay, their profile shows no gap - I'm guessing an eBay problem. Check local, and see about Summit, before you go, but if you're closer than I am, they may be a good try. (By the time I pay shipping, I'd be over the TCI price.)

Good luck.
