I had the Polar RS800SD for a few months and, to be quite frank, it's rubbish. If you spend over £100 on a distance watch you expect it to be accurate. I callibrated my Polar on a running track as instructed. I then did a 10K race and it recorded the distance as 8.3 KM - way off. Consequently I sold it and bought a Forerunner 305- the best decision I made. The Garmin if fantastically accuarate and motivating. What I love is downloading my runs on to the computer and seeing them run again using google earth. My advice: buy a Garmin Forerunner 305- you won't regret it. By the way the cheapest price is £189 in the UK is from GPS4less.co.uk
