You're talking full-on pro's though.. i'm talking "have a bit of fun drifting", which should read something like this!:
Chassis: HPI or Tamiya $200
Motors: Venom Fireball 13, 15 or 17 turn $30
ESC: Comes with the chassis
Transmittor: Comes with the chassis
Servo: Comes with the chassis
Batteries: Venom 3000mAh $29 each
Charger: $100 tops for a digital one
Power supply: wtf?
Tools: alen keys, tyre wrench, screwdriver. Come with the chassis
Tyres: rims come with the chassis, PVC is next to free
Bodies: yeah, if you change it, otherwise; comes with the chassis
So... $360 for the lot with one battery and one motor
That's affordable for just having fun without going hardcore =-]
