I would most likely push you toward the Midland BT2 the two largest reasons -it has a high volume level -does voice dialing, stereo auto Out of the Scala, xbi, and bt2, It also has the best audio quality, there are also upgrade speakers you can buy for another 40 bucks. ChatterBox is easier to work but has less features. I have demo units at Iron Pony that you can come in and play with. I would be glad to personally show you how they work and what the features are.We have the scala q2,multiset,teamset,fm,and solo instock, as well as midland BT2,BT1, ChatterBox xbi 1 and 2. Derek
