I bought mine for £80 including postage from a guy in the Russian Fed, it arrived in two weeks. Camera was in excellent condition, afew marks on the body but thats nothing. I was worried that it would be in bad condition but it runs smoothly, have had no trouble with the loop formers or anything. Maybe im just lucky?
You are always taking a risk buying from a country with a shaky economy so make sure you check them out before you buy. Ebay covers you for losses in certain cases. I find that the sellers who have their own business, good feedback and respond to your questions to be the safest bet.
Theres no way of really knowing what the camera will be like until you recieve it, check to see if they have a returns policy even though you will have to pay postage.
