Paul,
Can you provide any details on the  $249. angle of attack device?
Manufacturer, phone numbers, etc.
Many thanks,
Dale

Sorry no. Sounds high to me. A simple ribbon or piece of string taped on
the side window or canopy can probably do a pretty good job.

BTW I knew of a bush pilot in Baja CA that flew cargo in a large radial engine twin
into very short dirt strips.

What he would do was note the stall speed of his airplane (at a safe altitude of
course)
just before landing and calculate an approach speed based on that info. Perhaps
1.1 to 1.3 times the stall speed.

Actual gross weight was then automatically taken into consideration.
An angle of attack indicator will not give you that info.

Extensive discussion of this issue on the RV list. If you know your
a/c's AOA at stall, you can fly approaches using AOA instead of airspeed
at any weight. Navy flyers seem to like it.

I think this needs a wee bit more clarification.
The stall angle of attack (AOA) of a wing with a given aspect ratio and flap
configuration 
is primarily fixed regardless of how much load the wing is carrying.
The example I gave above was a way of doing it using just the airpeed indicator.
