The price was under $30. I read a review of it the other day. Seems this 2002 version is a little more complete than the 1997 version. The major complaint was that more information was provided for manufacturers earlier on in the alphabet (A-L) like Aeronca, Beech, Bell, Boeing, Consolidated, Curtiss, Douglas, Fairchild, Grumman, and Lockheed. And that's just US manufacturers.
Well, my response to that is that it just so happens that most of the major manufacturers that put out a ton of planes just happen to go by names that alphabetically come earlier on in the alphabet than others. Also, it a lot easier to come by information for manufacturers like Beech and Boeing than others.
Regardless, I can't wait for the next field trip to B&N! I gotta find another hidding place though.
