We have a '79 201 and have had it for 2 years now. We now have it
configured the way we like it. It has a Garmin 430 GPS/Nav/Com, Garmin
340 audio panel, Garmin 106 indicator, Stormscope, TrafficScope, King
DME, Garmin 396 w/ XM weather and STEC 30 AP w/ altitude hold and GPS
Steer.

The STEC's with GPSS are a real hoot. I recommend them heartily.
I've got a 55X (which will also couple to the approaches).
