New electronics and engine monitoring for old boat...

This summer I purchased a 1988 Pace 36 Sportfish that had been recently repowered with Yanmar 6LYA-STP's (370hp). The installation was brilliant, but the gauge package leaves a little bit to be desired. The analog gauges are inaccurate, including the tachs. (My engines are analog...)
I'm at a crossroads: Do I just replace the gauges with more analog gauges, hoping for resolution? Or do I look at newer technology (Maretron EMS 100 boxes) to convert my analog signals to NMEA 2000?

My electronics (gps/chartplotter/radar/ff) are all oldschool. Do I replace them with an all-inclusive system? (My pockets aren't megayacht-deep...)

If I used the Maretrons, I could purchase a display for engine functions or use an all-inclusive type of system for everything.

Any suggestions?

Thanks Cap! I'm looking at the Aetna's right now. That's probably the direction I'll go, regardless of the Maretrons. I'll use the NMEA 2000 as a backup. I like Aetna's combo units, too.

Thanks!

I went with the Aetna's, and am VERY happy with them! They are dead-on at all rpms, and are easy to read... top-notch product.
