If money is really tight, I'd go with (a.), but use one of the previous
generation of IFR GPSs like the UPS AT/Garmin AT GX-50/60 or the Garmin
GNC-300XL. They'd require an external CDI like the small ones sold by Mid
Continent Instruments. It'll install in the 3 1/2" hole using an adapter
plate.

If it fits in the smaller holes, I have two empty spaces for the CDI; one to the left
of my T&B, and one below it. I don't know how well the FAA likes the idea of putting
the CDI on the left side of the panel, though. I'll let my avionics tech decide that,
I guess.

With an IFR GPS, you'll have
the ability to fly to any intersection, so identifying them with dual VORs
won't be an issue.

That was my thinking too. Thanks for the leads.
