The S-Tec has been around a long time. They were once a reasonable option 20+ years ago. They were bought by Genesys and were the only unit on the market. I don't recall the specifics, but the price increased markedly. I was in the market for a replacement for the Cessna 300 in mine and as soon as I heard the uninstalled price, soldiered on with the Cessna until Dynon's autopilot came out. Despite the foot dragging by the feds, Dynon has done a tremendous service to the GA community with its autopilot offering. Tru-Track has also helped, and I understand they've been bought by King.
I agree with @M20Driver, the system is broken. The work that Dynon and others are doing, and their persistence will help fix it, but it will take time. I was at a lecture at OSH years ago when the Skyview HDX was first approaching STC using the approval mechanism Dynon is using. The speaker, in describing his role said, "Garmin took me off their Christmas Card list."
As for me, I'm very glad Dynon is continuing to press forward with the certification nightmare we all face, and I am very happy with their product.
