I can't say enough good things about how the one I flew behaved—it's a wonderful airplane. If you've never sat in one, the first thing that strikes you is the the volume of the cockpit. It's huge. The windshield arcs up overhead and feels almost like a quarter-skylight. The glareshield is monstrous.
I hopped in one on floats and knocked out three greaser landings, and I am nothing special when it comes to stick 'n rudder skills. It's just a great handling and very forgiving design. Flaps weren't even missed because the wing is so long.
Burl is truly excused from the Sedan space now, unfortunately. His site is blank. Won't answer the phone. Good for him, I guess, but yeah—it could mean that any meaningful support for the fleet is going to be found elsewhere.
My local Sedan buddy had a hell of a time getting support from Burl when his 180hp engine mount cracked. Then it was discovered that the mount had been produced incorrectly—several measurements were just plain wrong and it put stresses on the cowling and the thrustline was off. Ended up sending to a repair station here in MN to fix it.
That's why you have to choose the right specimen the first time, one with metal fuel tanks and as many STCs already installed as possible. There are many other aircraft types that are abandoned for support but people get by with generic components or owner-produced parts. Perhaps the case for owner-produced parts for the Sedan adds some extra appeal—now it's more akin to EAB!
The recurring spar cap AD is no joke. But it's documented. Aeronca club members remain a good (but aging) resource.
Find a Burl's aircraft thing that you think you can't live without, look into alternative ways to apply those mods.
