The current best options seem to be:

JPI 790
Would fit nicely bottom of my avionics stack.
Maybe I unconsciously had it layed out that way...

Upside - 'Simple,' lowest installed cost ( I think)
Downside - A ton of wires from engines, but sufficient to do the trick.

The other option

Suite of EI CGR units to replace EVERYTHING
Two CGR 30P, one for each engine, replace MP and RPM
and a CGR30C where Shadin is, to replace everything else

The appeal to EI is a hub in each engine and minimal wiring from there to gauges.

Going through an extensive annual 'wallet-ectomy' this year,
and replacing the last window (front)
because it's not as nice as all the other ones which are new 'solar grade'
