I use a HP G4050 Flatbed which will also scan negatives and transparencies up to 5"x4". Found it good for BW when I had an XP comp, but upgraded comp and use Windows 7 now and interface is more basic. Will scan optivally up to 9600dpi and 6x6 negs ,even at 2400dpi still give around 60mb files, 35mm about 24meg.
