I would highly recommend the SENA SMH10 units. I did my homework before buying, and these seem to be superior to the Scala and Interphone units. I used a pair for three weeks on a cross-country trip. The sets worked flawlessly and exceeded my expectations in every respect. Although you can't buy them in Canada, if you order from Rocketmoto (google them!) in the states you will have excellent customer services and perfect execution of the order.
I could talk your ear off about the Sena units, they are one of the few purchases I've made recently that I can give an absolutely unreserved BUY recommendation for. Let me know if you want more info on them, I can answer your questions from a user's point of view. The guys over at www.advrider.com have been talking about these for months and have a very detailed, extensive thread on the subject (in addition to discussing the Scala and Interphone).
