My riding buddies all have communicators, not sure what kind but they seem like a pain to me. They are always messing with them or have dead batteries, plus the battery goes in your coat with a cord to the helmet, I hate cords. I think if it were up to me I would get a motorola walkie talkie with an earpiece and a helmet mic. They're available I think from Cabellas. This way at least all that money and you can use it elsewhere than in your helmet. The communicators would be nice when riding with a group.
