Don't forget eBay and other used sources, I found a TL01, w/ all electronics for $70. It wasn't too abused either. If you buy used make sure there are a lot of high quality pictures to back up the item. If your LHS has a for sale board you could post a wanted ad for a used TL01 and see what pans out as well.

In all I'm into my entire car only about $120, and the car has bearings, sway bars, adjustable upper arms, speed tuned gears, lightened chassis and a P2K2 Pro stock motor. Good cheap fun!
