The Polar unit is wristwatch-style (mountable to handlebars) and you pay a premium for its compactness. The CatEye CC-HR200DW ($179; www.cateye.com) has many of the same features in a slightly larger, handlebar-mounted unit. It has all the usual bike computer features (average and max speed, distance, and so on) plus a wireless heart-rate monitor with a variety of measuring parameters and programmable HR zones. It doesnt, however, have the link-to-PC feature.
Lastly, Garmins Edge 305 HR plus Speed/Cadence Sensor ($430; www.garmin.com) does more or less the same thing as the CatEye, but throws in a GPS unit to track distance, indicate your location, and show altitude. The amount of data on the screen at one time is astonishingI even wonder if it presents a hazardous distraction. But for tons of info, the Garmin sure offers it.
