Fatblogging: hear rate monitor purchase

As part of my fatblogging effort, I just bought this Polar F6 heart rate monitor. I've had my eye on getting one of these for a while but this fatblogging effort finally threw me over the fence....that and an email suggestion from another fatblogger who encouraged me to buy one... Ahh...the power of word of mouth again!  It arrives this week. I'll let you know what I think...
