I run a chinesse radio 5W from http://www.dealextreme.com/p/dual-fr...-vhf-uhf-41618
and it is awesome It is run by kenwood 2 pin and there is lot's of headset that can go with as long as the plug is a kenwood 2 pin plug.
My whole setup cost me 230$ and I got a radio, professional troat mic, ptt module, and the radio to ptt cable, it is a modular, but the troat mic is the cheapest on that optherwise you are looking for a 200$ commander headset (it is a real deal for that and it had never ever let me down on comms with that.
for that headset. you WILL need to contact them and speak to them to buy one as they are on order only.
