I am riding a flatbar roadbike and using a Garmin 305...but it seems to be more complicated and offer a lot more features than I need. I would like a large print computer that gives me speed, time, distance and heart rate.

If I need a map, I will bring my pocket garmin with its maps...but just need something for riding around and being able to compare today's ride with last weeks.

Any suggestions?

what's your budget, have you looked at the Polar HRM/Cyclecomps ?
