The nicest F model I've seen recently is N2977L http://www.selectaviationservices.com/1967mooneym20fexec21.html However, it has been sitting as well. The Avionics are usable and has an autopilot. I don't know what the consensus is on its valuation but I think its close to being priced right. I'm just a casual window shopper and happened to come across it. I don't know anything beyond whats on the website.
