Garmin's GI-275: https://www.garmin.com/en-US/p/719027
This one 3-1/8" inch instrument displays more than 15 pieces of information, is somehow perfectly legible even in turbulent flight, _and_ is more reliable and accurate than a whole 6-pack[1]. Synthetic vision unlock is only $500. This is all without switching different pages.
Get two of them, and the FAA considers the possiblities of both of them failing at the same time so low, that you can cover one of them to satisfy partial panel failures in a checkride - well, all you do is to switch the "working" one to the PFD page, and you haven't really lost any capabilities!
