Soldato
Is that with or without foot pod? I'm assuming without.... The 50 is good, bought one for the other half and at £35 it's a pretty good price for what is a decent HRM. The 60 is likely to cost a fair bit more - so do you want something cheap and functional or the latest bit of kit with a few extra bells and whistles?
I'd prob say get the 50.
