I have no money, so I can't follow my own advice, but...

...rather than a Kiev, I would be looking for a used MF camera from a reputable manufacturer, if it was me. Those Kievs are cheap compared to a brand new, more mainstream make, but they cost as much as many used systems. I've done a lot of research on Kiev's, and, while they have many enthusiastic followers who are happy with them, they all seem to enjoy tinkering with them all the the time. The lenses are much more affordable though.
