get a losi or associated thats all im gonna say because I have driven both and they are both very good cars and they offer superior track side spares support as everyone runs them so most shops will carry lots of bits for them and you can pick an rc8b or a 8ight 2.0 up second hand cheap now and i would say a durango is an expensive venture (even second hand) if you are 'just dipping your toes in' to nitro. just my advice mate.
bit bias as i run an 8ight 2.0 eu and its awesome.
