Good advice, Jorge. I bought my first Hassleblad in 1980 for many of the reasons you cite. Used Hassleblad bodies are readily available now at very reasonable prices. The Hassleblad lenses (with the exception of the 80mm Planar), still have a lot of "sticker shock" attached.

jdef,
The Kiev is not a Russian knock-off. It is a Ukrainian knock-off (re-engineered) of the obsolete Hassleblad 1000F. I have an Arax/Kiev 88CM system which has been very reliable. The Ukrainian lenses are very good and there are a large number of excellent Carl Zeiss Jena and Schneider lenses that fit the mount (Pentacon 6TL).

These days, I mostly use it for film/developer testing.
