I have a Castle Mamba Max Pro with the Castle Link PC kit, and the Castle Link Programming card (for at the track programming without a PC), for $110 shipped. This would let you pick up the motor of your choice and still be well below your $200 price range. I used it as a backup ESC in my Blitz ESE and it has only seen a couple of race days on it. It worked flawlessly, but I'm now in the process of selling my Blitz and don't need it.

Let me know if you are interested. I'm going to post it for sale on the board in the next couple of days.
