I have seen the high end GPS units present a psuedo panel display (I am

It provides a DG/HSI presentation, GPS derived altitude, turn-and-bank and
vertical speed.

Has anyone experimented with this to maintain level flight in lieu of actual
gyroscopic instruments. I am *very*
skeptical of this, but have heard it suggested. Has anyone experimented
with recovering from an upset using it?
I would be eager for first hand experiences.

I am curious if anyone has played with a hood and one of these gyro
displays. Let me know.

I think you are late to the party. Please search the archives of this
and other aviation newsgroups and you'll find lots of people have
experimented with this under the hood. I think you'll find the consensus
is that in an emergency it can help you, if you're in a relatively
stable, slow airplane.
