I am doing a panel upgrade in January 2023, which I was going to leave the S-TEC 50 which has Altitude/Heading hold, level flight, turn coordination and GPSS equipped through the ST-901 converter all included.(No GPS) I would include all the servos has well. I was leaving it because it works perfect and if it ain't broke do fix it, but would love to have a new AP to go with the new panel. Not sure what a fair price would be you guys can through some numbers out there. Just remember it will not be available until January 2023.

If I do this complete upgrade I will have some radios to sale as well with VOR/LOC.
