The 505 sits in the middle of a three-unit range, and it's light, easy to use and backed up with great software.
The 3in screen is bright and easy to use in gloves,
thanks to decent sensitivity and large tile operating system. It's
water-resistant, with just a single rubber-covered button.
GPS tracking is accurate and the battery lasts for a
long day of riding. ANT+ allows wireless connection to heart rate and other
monitors (standard with the 600$ 505 HC).
The PC/Mac software is impressive, disgorging masses
of info clearly, and you can sync via wi-fi without going near a computer.
The downside is the lack of
off-road mapping, so navigationally it's only good for following downloaded gpx
files, traces you've recorded or roads.
