Do you mean mint -- as in never used? Or mint as in excellent condition? There is a difference.
By the way, I would be cautious about using a camera that has never been used. For a body, I would expect you to pay at least $1,000 from a dealer, possibly a bit less through private sale. For that kind of money, it's probably best to buy through a reputable source, or at least from someone that is trusted -- whether it be eBay, an Internet forum or someone at work
I would want something super clean and not much signs of use.
I read how Hasselblad is halting support for one of its digital backs afetr 6 years. Do you think Leica will contiue to support these older cameras?
