The 777 Sp1 looks like a nice piece of work. I just ordered one myself. I looked at a bunch of buggies and the 777 SP1 was my choice, the new X-Ray buggy looks nice and so does the mayhem, but the Kyosho buggies are proven to be the best, and they are reliable. I have a buddie that has had a K2 for over 2 years and has never broke a thing. He loves it, Kyosho seems to be the top buggy in my mind.
