I used to have a Plustek Opticfilm 7200, which takes a strip of 6 * 35mm negs - you push them through one at a time. Can also take slides.
I sold that and changed to an Epson v700 in order to be able scan 120 film; but the Plustek was OK for 35mm. When I sold it I think I got about £80 for it on eBay, I guess there will be many more for sale.
