Hi Fred,
Those are both nice looking planes, but I've got to say I like the Chief best! Everyone that I've talked to likes the O-200 conversion, it makes very good power. I'm intending on putting higher compression pistons in mine for a little extra power on top of that. I'm claiming my exp Champ to be the very first metal spar conversion, the guy who did the work went on to develop the STC that Milman has now. Otherwise it's a stock Champ.
The audio panel is a PS Engineering PMA-4000, part number 11942, so yes, I guess I did mean that. It was installed new on 10-11-2012. I'm seeing a price of $795 at Aircraft Spruce, how does $400 plus shipping sound?
Regards
Richard
