Anthony,

If you still want a Wisner, I believe that Midwest Photo Exchange (MPEX.com) has some in stock. They may be used, but that should not matter if they are in good shape. Talk to Jim when you call, he is the most knowledgeable and a really good guy. I have purchased a lot of used equipment from him. It has all been at least as good as described, probably better.

Quality Camera in Atlanta is another store that sells Wisner, or at least they did in the past. There have been good reviews on this store, but my only experience was to buy a rail for my old Cambo from them.

Of course, there are also other choices, like a Canham, Lotus, or Ebony.
