I bought my Garmin 305 GPS/HRM in October of last year at REI for $261 and used it probably a couple dozen times training for the Disney Marathon this January. I haven't worn it since Disney. It's lightly used and worked like a charm. I'm not a data junkie and I have a Polar HRM I used last season that I'm happy with. I have the box and everything it came with. More info: www.garmin.com/products/forerunner305/
Willing to part with it for $150 or a lifetime supply of Shiner Bock.
