I paid 7k total. The frame is the same size. It has fender flares that make it wider, and the bed is 3" longer. I thought about a 450 instead, but they were still more. I'm sure that the Scorpion, Sunl, diamo, qlink, and rouch are all the same machine. The diamo was cheaper, but I couldn't catch one in. For the cdi to interchange, it must be a close copy. I love it so far, I admit I'm nervous. I got it from a big tractor dealer here, and the service seems to top notch in case something happens. He sells them as fast as he gets them in, so he's pretty firm on the price. I tried to go $6500, but no go. I'm waiting on those 4" hid's from checkers, the headlights are so-so!
