I use a FireFox throat mic, Gander Mountain has them for about $30. That and a cheapie pair of FRS/GMRS radios, and they work great. I normally get about a weeks worth of riding out of a charge on the batteries, mine take 4 AAA's, I use Ni-MH rechargeables. Range is pretty good. At least as good as anything else. Zero background noise, and my friend that usually uses the other set has a piped '99 Mach Z with silencers. It uses a Push-To-Talk button that attaches to wherever you want it with velcro.
Sure, my "system" is probably not as durable as the chatterbox system or Colletts, but it only cost me $100 for 2 radios and 2 headsets.
