find your local track and see what they run there.
Little price brake down.
Competition Rolling Chassis $280 + ($380 is what I paid)
Competition ESC $160 +
Competition FM Radio $200 +
Batteries $50 + (per pack)
Motors $35 for stock, and $60 for Mod
Charger $150 +
If you want a high end servo $100 + (KO,Airtronics,Futaba,etc...)
This doesn't include tires,bodies,a solderingg iron, and you'll probably want some tunning options like spring,shock oils,motor bruses,specialty tools,a set up board, etc......
