Look at Aircraft Spruce and Specialty, angle of attack indicators.
Three different versions. Costly, but seems to have all that you guys
are talking about.

We have one in the 737-800 I fly, and never use it unless "heads
down." Captain has HUD with AOA symbology, speed vector and VSI, along
with a bunch of other crap, thats what we need, a HUD.
