I've been going back and forth between the Futaba 3PM and 3PM-FS Pro for a while. After a lot of debating, the 3PM seems to be the best bang for the buck. And since it will be controling my TC31, MGT and TC4, I also had to factor the cost of receivers. These high end radios that are out now have some great features, but when it comes right down to it, most basic radios will get your machine far enough away it's almost uncomfortable. The 3PM offers pretty much everything the recreational RCer needs, plus, it's HRS compatable. I like the idea of not have to deal with crystals, like the 3PM-FS Pro, but it seems like theres a possibilty of interferance. With a crystal, you're locked into the frequency.
