What was the total cost of the upgrade Scruzin?
I paid US $570 from West Marine. Fortunately I already had the SeaTalk-to-SeaTalkNG converter, but if you need that, that's an extra US $95.
There are definitely cheaper 3rd-party products, but I wanted to stay with Raymarine. It's also worth noting that the Raymarine product is more than just a remote control for the autopilot; it also lets you monitor pretty much everything on the SeaTalk network.
