Hello Kevin.
My name Nickolay and I Russian seller. Now have 1 K-3 in near NEW condition in carton box for 195$ + shipment. Probably you will become interested in it. If you have any questions on Russian equipment - I will try to answer you.
p.s. I sell on eBay since 2003. Sent still image cameras and movie cameras (and also the other equipment) in the different countries, and in the USA too. FOR all time of problems did not arise almost.
I have opened recently besides eBay the web-shop: http://store.siberian-shop.com.
Look, if it is interesting to you.
Here the reference on K-3 which I sell:
