I have a Mamiya RB67 original model. I guess I got it cheap, I got 2yrs out of it before the holes developed in the bellows and gotten larger, before that I also got some seawater into the focus screen so while it is workable it's not in the best condition. So I looked at getting it repaired, $80US for bellow replacements and then possibly $40US to have this installed for me? There is a older guy who has been doing this for some decades. It just doesn't really make sense when you can pick up the latest much newer RB67 Pro SD model with the focus screen in very much excellent condition for maybe $180US ...... Cheers. Edit. I have debated with myself that at least I have a working camera but for $40US more I could have a much newer body and the focus screen isn't affected with salt water and it does not have those rust spots on the metal body. Plus the original model does not have as much interlocks, forget to remove the dark slide - BAM! forget to crank the film mag - BAM! Even if I just buy another Pro SD body and have it sit on my shelf, it will just cost $40US more than having the old one repaired.
