Im sure Sam will chime in but I'll tell you before anybody else does. He doesnt due GP. One b/c his prices are really good for the product he sells. Not only do you buy the product, but you get his help and knowledge that come with it. Two, Hes already got the prices as low as he can get. The mans gotta make money, and has a business to run. I realize if Sam could do a GP, by no means would he have a problem selling 100 sets, myself included would be first in line, but he just can't. Hes got a lot time and money put into the parts and its part of the reason he doesnt. And third, with GP there is no guarantee people will actually step up the plate and pay for a set. Countless times, you get "count me in", "I want a set", etc. and you'd be lucky to get every person to actually pay. Just ask the other sponsors. Sorry man, not to be rude in anyway, but I just figured you wanna know before everybody else jumps in and then Sam gets on a speaks his mind.
