Thanks folks. That's what I thought: won't affect image, will affect value.
I don't plan on flipping it any time soon, but when investing this kind of change in cameras, I always want to keep that option open. That's what I like about Hasselblads, Nikons, Leicas: good resale. Fortunately KEH does have another one in Ex condition (they didn't have one the other day when I decided to post this thread). Thanks for the input, I'll be returning it. We'll see if KEH puts it back up as an Ex or a Bargain.
