Ironically, you missed the best value regarding radios in this price range. The Airtronics RD8000 is available from http://www.hobbypeople.net with a full flight pack all for $249.99. This radio is shift selectable (as is the Hitec Eclipse 7) so it can fly JR and Airtronics Receivers as well as Futaba, Tower, and Hobbico receivers. Unlike the other three radios mentioned by the original poster, the RD8000 is an 8-channel system that supports dual elevator servos.

Still, all of these radios have a lot to offer. The Hitec Eclipse 7 with Spectra frequecy synthesizer and a Hitec Supreme 8-channel receiver is widely available (without servos) for around $214.99 from a number of resellers; this is probably the most radio for the money available from the major manufacturers. The Polk Hobbies Tracker III Radio system with Seeker II receiver is also an outstanding value at $200.00

I own a Futaba 7CAF radio system and I have been quite happy with it. There are radio systems with more features available for the same or less cost, however.
