In reply to PTatts:
I'd go for the GPS, well worth the extra money IMHO
OK I've got the Edge 800, cos I wanted maps, but I'm sure the 200 would be good enough
I've had a variety of simple computers over the years and found them all to be pretty frustrating. Sometimes difficult to set up, often unreliable, all too easy to knock the sensor/receiver, and with wireless ones, the batteries don't seem to last long.
But the big advantage of the GPS is that you can upload the data, see where you've been, and store the details in Garmin Connect or Strava
Pity you missed the 30% off yesterday though!
