Hey, *I* want a DME!

But that's probably because the Warrior I rent doesn't have a GPS. The
DME makes life easier when all you (otherwise) have is two VORs.

Or is there something else that would give the same information as the
DME?

The point isn't that you don't need DME (well, unless you have a GPS), but
that it doesn't appreciably change the resale value of the plane.

I bet there are lots of used DMEs on the market from people installing
GPSes. I know we have one that we didn't bother to sell because they're
not worth much, so we're keeping it as a backup.
