Personally, I am a Futaba man. But only because that is what I have. I am a firm believer in keeping things the same. That way, I don't have to worry about what servos I can use with which system, etc. If you feel the same way, I would say that the JR XF631 ($199) is what you're looking for, If you don't care about buying other brands, look into the Futaba 6YG ($169) or 6DA ($179 - same as YG but also has mixing functions)
