Price is a factor, but so are the features. If you look at the ATD
sure it is low priced, but it also doesn't have near the features or
resolution as the other devices. You get what you pay for I think. If
you squawk any one of these codes, the ATD user handbook says it will
get confused and bounce back and forth between the target and "image"
target. http://www.airsport-corp.com/modecascii.txt I think it is
worth a couple hundred bucks extra to get better resolution and
accurate information, if you are going to spend that much anyway.

Loran,

What matters is portability, accuracy of the altitude, range, and the
overall size in my opinion.


Uh, price?
