There are on there like crazy. Someone will post one then the next day or two days later someone will post another one for $50 more. Most of them are X50's and the cheapest I saw was $175.
One person did admit to buying a V1 which will kind of ruin your sale if you're not careful. I would say something like I never used it or it was given to me but fill in the blank. Who knows, that's just me!
BTW, I love this new format for the board! Being able to pick your own font is cool as hell. I always change it to Georgia from Verdana. Is there anyway to default to Georgia instead?
