Avoid Schumacher...hard to get parts for, expensive.
HPI for the win....American brand, so its CHEAP CHEAP at the moment. Don't get ripped off here, buy everything from Tower Hobbies (
www.towerhobbies.com).
They are cheap and reliable, I've spend thousands with them over the years.
I recommend the monster trucks too, they are brilliant fun. Good all rounder if you wanna bash around and do jumps. 1/8 buggies are more for racing, not quite as fun as a truck for jumping and mucking around, but they are VERY quick.
