I currently have a KO PROPO VFS-1: Hara Twister 2. It's an execellant speedy, well worth the money. I'd try for either a second hand race quality speed control or look at some of the older Novak Models like the Novak Cyclone TC2. They are still good speedy's and would serve you well.

With a speed control i think you should go out and get a good one first up then as you progress you won't feel the need to change it as i did. I only started racing last October and have had 4 speed controls since then, thats over $500 pretty much wasted.
