Here's a plug for the SN10: I have one in my Ventus 2. I've flown it for years. Now share an Arcus with the new"Uber" display. I surely miss the SN10 navigation page which simply and clearly displays all data needed! With the SN10, I fly with the navigation page displayed 95% of the time. Simple, uncluttered, just what an aviator needs. Need a moving map? Just look out the canopy, where your eyes should be, anyways. In many ways, wish we had an SN10 in the new Arcus.

That being said, if you fly in complex mountainous territory, such as the Alps, where there is a paucity of out landing fields and airports, a good moving map display really does offer a significant benefit. There, I fly withe the SN10 and a PDA running PocketStrePla. The PDA gets data from both Flarm and SN10. Flarm is mandatory in Europe, and a great help in the glider congested classic routes. I'm a big fan of Flarm, and from experience,can say it is a great benefit. Just to clarify: 60% of my flying is in the Midwest USA, 40% in the European Alps

You are spot on: at current second hand market prices, the SN10 is unbeatable for value
