Prest400... Yes, I'll be keeping the Rolleicord just because of the history.
Karlovak... the aperture and shutter are linked so that one can work with EVs. Also, my Rolleicord has a button for a shutter release. This means that a photo can be taken by pressing the button or pushing the cocking mechanism sideways. Quite nifty, I thought.
JSRockit... I can't argue with you on that one! I'd agree... lucky!
