I'm tossing a coin between PS Engineering PM 1000 II or the Sigtronics
SIC-4

Does anyone have anything good or bad to say about either one?

I had a 4-place PM 1000 II installed when I bought the airplane in 2000.
It has always worked well. It has the "clearance recorder" option which
has proved handy on occasion.
