Wanted: Garmin Edge 500 & 52/53T Chainring

[willhub]

Looking for a Garmin Edge 500, possibly with HR &/or Cadence.

I am also looking for a 52T or 53T Chainring to fit a compact chainset.

Pref second hand for the Garmin, in fact for the chain ring I'm not bothered if it's second hand, as long as it's got plenty of life left in it.

Thanks.
