It's tough to beat the deal at http://www.hobbypeople.net where they're selling the Airtronics RD6000 transmitter with receiver for $99.99. It's a really nice full-featured 6-channel computer radio with a lot of advanced programming and mixing features.

The upcoming Spektrum DX6i looks like a really good value at $179.99. It's a full-featured 6-channel computer radio like the RD6000, but it operates at the 2.4Ghz Spread Spectrum range.

These are two of the best values available today. Good luck and good shopping!
