Recently I've been in the market for either a 2000fc m/w or a 2003fc m/w. I have come across some one eBay and I've read to be weary about the condition of the shutter curtains in the back. My question is, what kind of condition is bad? All of the curtains that I've seen have wrinkling in them to a certain extent. Is this just from normal signs or wear were these accidentally damaged by the owners? I have read about a Hasselblad repairman that's been making his own hybrid version of the shutter curtains so I might consider getting it repaired if it's that bad.
