I wouldn't spend the extra on the Eclipse. If you're going to spend a lot for a computer radio, get something closer to 'top of the line'; like the Futaba 9C, or the JR 8103(?), OR the Hitec with the 'Spectra" (?) module so you can change the transmitter channels.

Otherwise, either get a basic 4 channel or a less expensive computer transmitter like the Futaba 6 series.
