I don't know about prices in Sweden, but in the US I would think that is too much, particularly if it is the original version. I paid $135 for one with the normal 90mm lens and got to inspect it and try it out before buying. It also had a back and the waist level finder. I have a 250mm lens, but I find it less useful than the two more normal lenses - the 90mm and the 127mm. Also, there are several versions of the lenses, some considered better than others. I'd recommend you do some more research. There is a US outfit on ebay that sells a lot of RB67 stuff. Also you might try keh.com. I don't know if they ship overseas, nor how much shipping would be, but keh is a very reputable company.
