I found a motorcycle to motorcycle communications package last week while surfing the web and decided to buy it.
Its made buy Nady and works as a motorcycle to motorcycle communicator and as a driver to passenger communicator (you just have to buy a second headset). You can even plug in a music source like a CD player. I have not had a chance to try it out on the road yet but the helmit speakers sound sound pretty good for voice communication (the sound quality reminds me of a pilot friend of mines headset).
Here is a link:
At only $61 I though it was a pretty good deal and wanted to let you all know about it.
