Epson Expression 1680
The Epson Expression 1680 is an "old school" flatbed scanner, which means it's big and weighs a ton. But it's well built, and accepts transparencies up to 8x10". Not bad! Resolution is 1600dpi, which may be limiting for 35mm but will do a good job on medium and large format. You can also use it as a standard reflective scanner for drawings, prints, and more. It connects via standard USB or SCSI, believe it or not. Includes a set of mismatched-but-functional holders for 35mm negative and slide, medium format (up to 6x12) and 4x5. Includes power and USB. Note that you may need to purchase additional scanner software (like Vuescan) in order to use this scanner on modern computers.
