FS: Polar RS800sd HRM Watch

This watch was used in training for 2 months. I baby my gear and its in mint cond.
Comes with HR strap, watch, polar training software, S3 stride sensor. I can through in a IRDA interface to read info from watch, not as nice as polars but it works. Retail value $500.

asking 400 shipped or possibly a trade: looking for some clincher race wheels (+ cash if needed), cranks, DA cassette 12/25.
