As a Binavi owner and having used for all sorts, touring / racing etc this year, it's superb value and highly recommended. ~ £169 from Amazon (UK)

But not without some gripes/minor improvements (I'm not complaining at the price point!) -

 - A more vibrant screen
 - Strava Segment support
 - iClimb when not riding a route
 - Ride sync to Strava direct from unit (not via app)

All minor points for me^ . Wasn't sure if the iGS800 had a better screen though?
