What about 1:72? (Because my first serious model project since- well, ever- is a 1:72 scale B-36, I've decided to therefore model exclusivley in 1:72. And yes, I know I can't spell) While browsing a WWII textbook, I happened upon a photo of (for me) a previously-unknown German aircraft- the Me 264 "Amerika" bomber. And whaddaya know, Special Hobby offers one- in 1:72, no less! Talk about less than mainstream!
(Or maybe it is, and I'm horribly sheltered!) I found that kind of cool. Now, where to get the 30 bucks...
Another interesting 1:72: Zveno. (Russian parasite program using a TB-3 bomber and two parasite fighters. I forget which kind. I-16s, I think.)
