Time to replace the KNS-80

Well it looks like it's about time to replace the old KNS-80 RNAV.
That thing has had a lot of use, it's getting old, and it's been in
the shop a number of times.

Currently the frequency selector appears to need cleaning, but I'm not
sure how long it has left.

So, I'm looking into a certified GPS that will fill the hole left by
the KNS-80. It's also going to need to drive the GS/Localizer head.
Not being current on GPSs I see what appear to be a number that would
probably work.

Any socially acceptable suggestions?
