This happens to me all the time. Just when I save up enough money to buy a Mosin I always find at least two rifles that I must have. I would get the sanitized version first. I think it'd be easier to find the Tula 91/59 later on if you'd like. However $135 is a very good price for ANY 91/59 so if you have some extra cash then I'd get both of them for that price. Get them quick because they may not last long. Good luck and post some pictures when you can. Aleks.
