I used to train with the Garmin Forerunner 205 and I really liked it. It measured my HR, distance ran (biked or cycled), had stopwatch features, calculated real time pace also. It was pretty large, but I liked it. I sold when I took a hiatus from working out.
Now, I just bought its younger brother the 305. Same basic functionality, in a smaller package, and I think some upgrades in so far as connecting to satellites faster, etc.
Amazon has it for $160 shipped, I got it off Slowtwitch forum for $100 shipped.
