Patrick,

I don't want to berate any of my competitor's products, but I felt I should point out what I believe are significant differences in features and capabilities.

Budd Engineering angle meter:
The AeroPerfect does not require an initial calibration procedure before use as does the Budd Engineering meter.

Budd meter doesn't lend itself well to making comparative angle measurements such as when setting elevator halves as the measurement stand would have to be moved for each elevator half (Comparative measurements with AeroPerfect are made by simply pushing a button).

Budd measurement stand must sit on top of a flat surface near the control surface (AeroPerfect's digital readout can be placed anywhere within 6 feet).

Budd measurement range limited to the height of the measurement stand (AeroPerfect's is 360 degrees- great for extreme 3D throws).

In terms of value consider Great Planes AccuPoint Laser Incidence Meter has similar components and costs $19.99 at Tower Hobbies.

CRC:
Great value and allows comparative measurements to be made easily (such as matching elevator halves). It's measurement resolution is limited (1 degree?) and care must be taken to avoid parallax errors. AeroPerfect’s meter is .05 degrees (or 1/20th degree over a 360 degree range).


Hope this helps in your selection.
