Not sure if I mentioned it in here, but for IN only, it is hard to beat
the open-software stratux. Less than $120 for everything. Or make it
as fancy as you like. :)

It's still early days yet in this area.

instrument though you should consider upgrading to the Sport EFIS with
the bigger screen.

I didn't even look at GRT when looking for a portable attitude

The GRT mini is very nice also and can be used as a full blown EFIS or

Using the vacuum from the intake manifold is something that used to be

The electric vacuum pumps (for the brakes) from the mid-90'
I think I like the idea of an electric vacuum pump. It's easy to have a
backup, and keeps working even when the engine doesn't.

The electric vacuum pumps (for the brakes) from the mid-90's 'Vettes are
about the best out there. I put one on my Mustang II. Very durable.
Not too expensive.

My Bellanca super Viking had one instrument to the intake manifold in for
emergency only. Full throttle I had almost no vacuum. Only drove my turn and
bank. Not enough constant vacuum on your intake. Most airplanes with a full set
of instruments requires 5 inches minimum.

Manifold vacuum isn't something I'd depend on. As engine load goes up,
manifold vacuum goes down. I'd worry about instruments getting good vacuum
on climbout. If the engine cuts out, your manifold vacuum will drop as
well (even if the prop windmills). Using exhaus
