lilman,
Wanna know my best kept secret over the last 14 years?
Danny Thompson at Performance Toys. His number is 704-485-6242.
Lee Sheirts, Gann, Carolina Cycle and the others are good, proven builders, but Danny does not have a huge overhead like a lot of the others do. As a result, his costs are less.
He won't try to convince you to buy parts you don't need, either. I know from experience.
Give him a call before you make a final decision.
Hope this helps.
