This is what I bought.
a set of midland 2 way radios. Voice activated (VOX), 7 mile range, very small design, water resistant.
Cost, $34.00 from Best Buy
a pair of microphone ear pieces
Cost, $17.00 from the web amazon.com Free S/H
So for $50 I basically got two chatterbox units. That have a far greater range, can be used without the helmet, and do not need to be fitted to the helmet. So no one even knows your communicating with other riders.
They work great, fit great under a helmet, and its so damn cool.
You can communicate from rider to rider or rider to passanger. Hell, you can even get 2 sets and ride with 3 other people and all stay in contact. I did notice that it says the range is 7 miles but it's really like 2 or 3. They have another set that is about $70 and says it has a 10 mile range, so that one is really like a 5 or 6 then. but that is damn good.
I also opted for a battery charger options.
This was $25 and also from Amazon.com .It came with 2 battery packs and a duel slip in charging craddle. I figured the batteries would cost more then $25 in a year.
I couldn't be any happier with these.
The model # of the set I got was G-227 and the G-300 is the one that claims 10 mile range. The model # for the set of handfree kits is AVP-1 and the charging system is AVP-2.
