I have been very satisfied with the EI MVP-50 in my Bonanza; if your panel plan does not include fabricating a large square place for the instrument (and I get that some folks don't want that), the CGR30P performs all the same functions in a 3.5" round form factor.
It integrates very well with your GPS, and (in either device) is primary, so you can remove older gauges - and you won't be looking down by your left knee to see if you have sufficient oil pressure or fuel, plus, no more oil dripping on your socks.
