Well I wouldn't be that quick to purchase one. While I absolutely love mine, If you would prefer a counter-steer drifter, want to build a racer later, or some other reason, then we could make some better recommendations.
If you feel good about it though and did some research, I bought mine new from ebay:

There are a few bodies you can choose from in that price range. Anything with TT01ES , RTR, a body you like, and a good rating is probably okay. Be aware that most of them do not include a battery and charger, and do not include drift tires stock. (Unless you buy a designated drift edition, slightly more expensive) I made drift tires using PVC pipe. Good luck
