IMO if you want nitro save up another $100 and get a Hyper 7 as the 1/8th scale nitro buggies are built like tanks. I wouldn't go cheaper for nitro as the cheaper engines tune like crap.
Tamiya has the DF-02 kit for $130ish (the $164 has a better ESC included) you need a radio, servo, battery, and charger. There is also a cheap $5 mod that is almost mandatory to do or the hinge that holds the arms on will rip off the chassis(that is the only real issue I ever had, and I got mine going over 4X faster then it was designed
) Its a 4wd buggy (I own 2 of em). After I did that mod I've not broke a single part on it.
If you like MT's HPI has the Wheely king for $215(last I looked) RTR umm could use a better battery, and charger as the included ones are kinda crappy. Just note its a monster truck, and drives like a monster truck, and the name of it is pretty accurate description
There are some RTR's 2wd vehicled by ECX that are pretty good value for the cash that are under $200 (only thing mentioned I don't own, but known people on here that have)
The mini revo I own one I find it blah in stock form. IMO it needs upwards to $100 in aftermarket parts to make it decent. (I own one)
