Rc nitro buggy kits?

I want to build a nitro buggy from scratch. i think i want to get a kit or something. What is a good one to get, and could i have some links for them. I dont want anything too expensive, although i know they arent cheap. I have built electric cars and trucks before and i want to start building nitro buggies. aslo, any tips for building it would be great!
-Thanks!
