Bill gave you some good sound advice. Personally, I don’t care for or recommend the cheap off brand trucks - especially for racing. I would follow Bill’s advice.
I am strictly a basher, but awhile back I wanted to get a Truggy. I’d never had one and wanted to see what “all the rage” was about. I put a want ad up on RCTech that I was looking for a used Truggy. A spectacular fellow offered a very low time TLR 8T 3.0 to me and was willing to meet my budget limitation. So if you do a little research to learn to know what you need (and be realistic), you will find a plethora of people willing to help. Getting into racing isn’t cheap. If you have a tight budget, you might need to rethink your goals.
