If my GNS430 tanks and/or becomes too expensive to repair, I'd have to seriously consider a slide in replacement IFD 440. The modern screens are much higher res than the 430 screens. Shoot, even the Lynx NGT9000 screen is higher res than my 430. BTW who provides the database updates for the Avidyne units? One nice thing about the Garmins is that they recently drastically reduced their database prices compared to Jepp.
