My Epson el-cheapo flatbed scanner with 35mm film scan attachment can scan to TIFF files, not just JPEGs.
However, I think a good macro closeup lens on an interchangeable lens camera (dSLR or u4/3), especially a lens with little off-axis distortion, would easily work on a light box, with a homemade black foamcore board light shield "pyramid" betwixt lens and light table. This will probably be the future of film scanning, such home-spun rigs.

of course Joe. i have a dedicated scanner that does a bloody good job of 35mm, 120, 4x5 etc. and will scan to tiff and a few other options. however when the response is held in context (in regards to Greg's post {one up from mine}) it is very difficult to visualize the advantages of a high end scanner on Flickr, or elsewhere on the web, due to the compression needed.
