eCoach has now also support for Zephyr HxM bluetooth heart rate monitor. It costs around 100e...AFAIK polar doesnt currently sell bluetooth heart rate monitors, they have only one model which was bundled with Nokia N79 active. Its true that bt HRMs are still a bit expensive compared to normal RF only HRMs. Info about Zephyr HxM http://www.zephyr-technology.com/hxm.html //Sampo
