I must be insane.
But check out the Diana Mini.
I know, the half-frame thing is a gimmick, and one can make square photos of rectangles in Photoshop (or at the very least, with a pair of scissors).
But still, it's very cool.

Personally I've always had good luck with cheesy plastic caleras - my most favorite photo ever (the black and white one of Stonehenge) was taken on a $6 Vivitar Ultra Wide and Slim.
