Cardo Scala Rider Q2 Multiset - Bike to Bike Intercom

We are considering getting the Cardo Scala Rider Q2 multiset bike to bike intercom system, to replace out old Chatterbox system. As well as bike-to-bike comms without the UHF radio, it also allows for connection to an MP3 player, receiving mobile phone calls by voice command, and connecting in a GPS system to hear the audio through the headset. Does anyone out there have this system? If so, what do you think of it? Is it worth the money? Good quality sound? How is it under noisy helmets and does the wind noise cut into the audio conversation? Any other comments?
Pro Accessories have the sustem for $659, Pro Honda for $680. Online it seems MUCH cheaper, LBH Retail have it for $479, Mr Gadget Aust has it for $492, and Ryda has it for $491.
