RE: WHAT CAR FOR DRIFTING!!
$300 USD will get you a pretty good car.
XMODS they are really small, they can fit on your palm*, They are fun and all but personally I wouldn't say they are "Hobby Level"
I suggest getting a 1/10th scale car, RTR (Ready-to-Run), If you havn't had much time with RC cars.
But if you have had experience, go with a kit, they are around $100-500
For a radio, go with brands like Airtronics, Associated, Futaba, Hitec, etc.
