Garmin Forerunner 305 for sale.
Includes unit, chest strap, charging/interface base and connection cord. I do not have the software cd, but you can download all of that from the Garmin web site. It also includes the bike cadence sensor unit. Less than a year old.
$200
I just checked E-Bay, which I should have done first. I'm lowering the price to $125, plus shipping.
