I have a complete Sandel SN3308 system for sale for $2500. Includes SN3308 Software V2.11, tray, connectors, data jack, dimmer pot, gyro and fluxgate. These are still very nice systems, not too difficult to install and not much more than a new ILS indicator. I've recently installed a similar system in my C172 and it really helped clean up and integrate my panel. See my album for pictures. And if you are headed towards an all electric plane, all you need is this and a G5 (when they start shipping). Also available with a nice Garmin GNS480.
