Before buying a Kiev go to
And check out the kiev report forum. It is a nice bunch of folks and very willing to help out. And they love their FSU cameras
I am assuming you are not in the US. If not then contact Arax photo. www.araxphoto.com at this time their cameras are getting really good reviews for reliability, moreso than any seller in the states. They might be a little more expensive but the warranty and service are definately worth it not to mention the likelyhood of getting a working kiev. Buying used can be scary though I have been very lucky.
My kievs are my only SLR MF system and I have been more than impressed with the very inexpensive glass.
Good luck and definately stop by the kiev report forum.
