I could make recomendations, but frankly, I haven't seen a bad ARF trainer recently. The RCM is goo, the Tower, Hobbico, and Hanger 9, are all good. I personally look to World Models first for any ARF, and their trainer is verry nice.

Check with the LHS, see what they have. In the 40 range, $150 will get you anything out there, most are right at 100.
