Not me. I am VFR

With VFR any non-certified hand-held is plenty good.

With IFR WAAS (145/146) gives you LPV (much greater access, and
increasing all the time), and you get VNAV minimums on VNAV/LNAV IAPs,
and you get safer vertical guidance on LNAV only IAPs. Lots more safety
avoid dive and drive.

True but plain old non-WAAS Garmin GNS 430 offers adequate approach
functionality.
