James "DarkAllison" in KY used to have about as clean a XTB as I've EVER seen & he had it for sale after he bought a XB-21. I never heard if he sold it yet or not?
Lundy in Iowa has a BEAUTIMOUS XTB as well. Talk about a peach, I've admired it the last two years at the Clifton Rally. Lundy always says he wouldn't sell, but then DOES!
