Looking to buy either of these two? The Garmin Edge 510 being $100 more is swaying me towards the Sigma ROX 10.0. Any input as to why go with one instead of the other, will be appreciated. I currently have a sigma 1609 and have had no issues with it, but I am looking to move up into a GPS unit. Thank you.
