"It currently has no artificial horizon installed, which I would like to
have before I do any night flying, as well as no turn & slip. The previous owner was considering adding an Enigma EFIS to the panel, . . ." I put a TrueTrak ADI with GPS track readout in my small panel and I'm real happy with it. Gulf Coast Avionics had the best price. http://www.trutrakflightsystems.com/instruments_ADI.htm If I had the room however, and the money, the Enigma EFIS you are asking about looks like the cat's meow. Chalkie Stobbert used it on his recent successful Cape Town/London/CapeTown Henshaw Challenge GP-4 flight. Plus, I think those two fellows who just flew their "Sling" around the world had two of them installed. Quality of South African made products is generally excellent. I agree that you need some kind of attitude reference in the plane. Before I put the TruTrak in I had an unreliable electric turn coordinator and felt very limited in capability. The ADI is simple and reliable and relatively inexpensive. It includes an inclinometer too.
