Quick question - I'm internet shopping for a new networked GPS/ff/radar system. The Raymarine E80 I've seen in person - and the display is fab - very bright and sharp. But I really perfer the Furuno Navnet features (particular the ability to do integration with a PC via ethernet). Question is - what do you think of the Furuno 1720 (7") and 1920 (10") displays. Are they they any good?
