I refuse to call Bob Banka's service a source of "3-views"
-even if that's what he calls it himself.
I prefer to think of his services as aircraft modelling documentation. When I order from him, I choose the "better" plans... scale drawings,with cross sections, details, etc., that you cannot get from a 3-view. Additionally, he provides photo-packs...
(which reminds me - John - did you do the Japanese transport for the Confirmed Kill beta?)
You can get "3-views" from just about anywhere... from Banka's service, I get scale drawings.
After 7 years of aircraft modeling, I'd have to say the best source of 3-view drawings is at:
http://www.bobsairdoc.com/3-view.htmWhile his drawings are payware - they usually cost from $3 to $5 for a set of drawings - they usually are top quality and are just what the modeler is looking for. He has 38,000 drawings in his collection. They're usually scans of drawings that originally appeared in various aviation magazines around the world.
I love books, but I rarely have been able to get a good three view out of them. They almost always have the drawing too close to the spine of the book and you get a distorted image when you try to scan it.
A quick search on Google usually produces some good results as well.
