I recently bought a Rolleicord Vb on ebay and paid 200euros (150$, way too much!) - it turned out to badly need repair which cost me another 300, so now I probably have one of the most expensive 'Cords in Europe! But it takes beautiful pictures - and I don't think I would be better off with a 'Flex (except of course if it were a 2.8 ).
