PCFlight Systems sizes their portable unit to fit into a standard 3"
instrument hole (wink, wink). I was told the odds of getting a 337 for the
thing were about zero. I asked PCFlight Systems if they had any plans to
invest the $50 - $100K it would take to get an STC and they just laughed.

Ah, the FAA, busy enshrining mediocrity.

Tell you what, if 100 people on here each chip in $1000 I'll put the money
into an escrow account, get the 337 and then sell you a unit at cost. Think
of it, you'll own 1/100th of an avionics company!

Thanks. Just checked out the aviation consumer article. Great
information. I have a call into the local FSDO. We'll see what they
say about the panel-mounted unit (e-Gyro-3). I do seem to recall
someone in the mid-west that tried to put one in with no luck. Maybe
the people in Maine will be a bit more helpful.

Regarding the portable units, the gist is that they're capable enough if
you're in a bind. In fact, even something like a Garmin 196 would
probably
get you out of trouble (at $999 though, you won't save any money here).
Depending on the flying you do, they also recommend keeping a spare pump
around (they estimate $300), otherwise if you're away from home you'll
either be going home VFR or paying some unknown shop to replace your
pump.

Regarding a 337, it seems to depend heavily on your FSDO. Which company
offers a panel mount option?

I'm part owner of a IFR 172E. Nice equipment, but no vacuum redundancy.
I know I can add a dual-rotor vacuum pump or a manifold-driven
alternate vacuum source, but I'd rather have an electric backup (in case
of engine failure). Electric pumps add weight and good backup electric
AI's are expensive. Does anyone have any experience installing/using
the new solid state gyros? I have an iPaq and handheld GPS, so the
"portable" units would be OK. One of the manufacturers has a panel
mounted unit, but apparently it can't go into a production plane. What
are the chances of getting a 337 for that if it is for backup only? I
can do partial panel, but I'd rather have the most capability that I can
get (within reasonable expense).
