A couple of items that seem to be going up these days:
1) Rollei 35 cameras of various versions, especially the ones with the Sonnar lenses (35S and 35SE).
2) Lenses for Kiev 60 cameras. The cameras themselves seem to be up in price a little, but the lenses seem to be up more, especially the ones that are non-normal in focal length. Also, I have noticed that a lot of the systems are now broken into components rather than complete (body, lens, prism...)
