Bought a new Polar CS200 from Chain Reaction Cycles online. With cadence and HR monitor for +/- R 1,200 with VAT. Great computer and value, only thing is that if you want alititude and graphs of your ride you need to go for the CS400. CS200 is compatible with polarpersonaltrainer.com so you can upload your rides and it keeps a diary etc for you. If you want you can also link via this site to discovery and earn vitality points for your rides like for gym sessions.
