I think with the solid reputation alongside high quality and excellent track performance a mugen has to be the pick, I honestly beleive its one of the best if not the best buggy and the amazing thing is they are now one of the cheapest to buy so if you ask me its a no brainer what id buy if i had to make the decision,
MBX6 @ amain hobbies for $479 which will require absolutly no upgrades what so ever to make it a great buggy to race
... Awesome
