In reply to FesteringSore:
I use a plustek 8100. Its pretty good. If you are only doing black and white then there is no point shelling out more for the 8200 as the only extra thing you get is scratch removal and so on. This feature cannot work with black and white. I got mine from Park Cameras.
Its a bit of a job maybe 2-3 minutes per slide/negative. But getting it done where I live is 9.99 a roll. So well worth getting one.
