I’d like to get something worthwhile, but without breaking the bank or having the plane at the avionics shop for a month. Is there a reasonable gauge with good CHT & EGT readouts or is it best to spend the $$$ and get two EDM 830’s.
Thanks,

Tripp I have the Insight G4 and it provides a tremendous amount of information in a small package for a reasonable price. So far I've had to replace one EGT probe and that's it. One of the nice things about Insight is that they ship with Skymaster specific harnesses.

Having said, if I had to do it again I would go for the JPI EDM960:

In addition to that, I would go with the CIES fuel senders:

If you do JPI + CIES...it means that EVERY SINGLE old gauge goes right in the garbage can and you have accurate, digital monitoring of every engine parameter and the fuel quantity.
Yeah, it's a lot of money but I've spent lots of $$$ in labor this year chasing old wiring.
