ofna 1/8th scale buggies are probabl the best band for the buck. They cost around $300, and honestly can take a royal beating
Jammin X1x CR from amainhobbies.com is $300
Ofna Hyper 7 TQ Black is $299 from towerhobbies
not sure if they are in stock though last time I looked they both were outta stock


As for the rustler it should run if you get a new engine assuming nothing else is broken that is.
