I picked up a K3 fairly recently to run myself. Shortly after there was a 777 here in the for sale thread for $300 roller. But no biggie, I got a nice bag of spare parts with mine, and it was put together by one of the best racers around here.
I'm beginning to think I have to many rc cars sitting in the basement though... Going to have to start storing a couple where I can't see em so I won't think about it...
