there is another thread on this blog called "radio help", there might be some help for you there.
Do you have any $$$ limit? That makes a big difference on what you well be able to look at. I have a JR radio in the 2.4 system, I think the spectrum is the best way to go. In the Spectrum line of radio's , I think the DX7 is the lowest one I would want.
There is nothing wrong with any of the other radio's I just have a JR and like it.
