Pentax 110's and Exakta's are my favorites. 
 I wouldnm't call the former a 'favourite', although I have 3 or 4
 of them
 with an assortment of lenses, flash, motordrive, etc. It's
 certainly an
 interesting camera, although too much electronics (and no manual
 override) for my taste.
 But Exaktas I love. I generally describe them as the 'Citroen DS of
 35mm
 cameras' (if I ever learn to drive, a DS is top of my list of
 desirable
 vehicles...). The Exakta is totally unconentional. Every control is
 where
 you don't expect it. But then it has shutter speeds from 1/500 (or
 1/1000
 on later models) to 12 _seconds_. A film cutting knife (and you can
 run
 cassette-to-cassette) so you can cut off an process part of the film.
 Interchangeable viewfinders (I must repair the metering prism I
 have for
 mine -- alas the meter coil itself is open-circuit). And so on.
 Among the 35mm Exactas around me at the moment is a VP exacta
 taking 127
 roll film (6*4,5 cm frame). Yes, I like them...
 -tony 
 pentax  110's are such a fine example of Japanese engineering.
I have two VP's.  one black one chrome
exakta 11a's and b's and a VX1000..  And behind them are the
Periflex's  another unusual design!
Enough of this, we are waaaaaay off topic!!
