Hasselblad Bron is very annoying to extract a quote out of. I emailed asking how much to change a focus screen on a 500c and they said they couldn't tell me until they saw the camera "because it may need alignment." Maybe they didn't understand the issue, but I think no matter what, when you change a focusing screen in a camera like this it will need alignment! That is entirely the reason I'm not doing it myself. Also, would it really be so difficult for them to give me two numbers, one "without alignment" and one with? Luckily I found a local guy with an optical bench (anyone ever heard of Camera Center of York?) who will do it for $60.
