Here's where I'm at now.
I was interested in checking out IFR GPS units as a DME alternative.
You can get an older (KLN 89/B) unit pretty inexpensively.
So I went to my local avionics guy and talked to him a bit.
After explaining what I wanted to do, he actually recommended going the DME
route.

For an older GPS, I'd have to get another indicator to slave to it.
He also said installation costs would go up as a result.

He said the best solution (cost/complexity-wise) would be to pull my ADF and
put in a DME.
If the avionics guy is telling me this is lower cost/complexity, I guess I
better think about it!

So now I'm thinking of two choices.

1. Find an inexpensive DME. I'm thinking either Narco 890 or King 62/64.
Definitely not a remote unit.
2. Find an inexpensive IFR GPS with built in CDI (kind of like a King KX-125
NAV).

If anyone knows of such a GPS, I'd appreciate it.
If anyone knows a source of great used avionics, I'd appreciate that, too.

Oh yeah. One other alternative I was thinking of was using a KLN 89/B for
enroute only, no approach.
That is, using the GPS sort of like a DME.
Is this legal? Can you do this? The only reason I ask is that I can find a
KLN 89/B for less than a DME 64.
