I get on my bikes to get away from talking to people.... - probably why you don't have more interest
I thought the same thing till I bought one last year. Last fall about eight or nine of us want down to Arkansas and one guy want down on Push Mountain. I was able to talk to the guy leading the pack to tell him we had one guy down. With out it the guys up front would of been sitting at the end waiting for someone to go tell them the bad news.
The best pricing I found was at Chatterbox X1 Slim Extended Range Wireless Intercom | Cli-MAXRidingGear.com
for $290. They also have the FRS X2 for $140 and the GMRS X1 for $160
