Forced for practical reasons to ditch my old Epson Scanner (a SCSI) I bought an Epson Perfection V100.
It is miles better than the old, cost about £60+ from PCW, (less than a third the price of the old one)and a bonus for me makes very good scans of old 35mm film and transparencies.
Snag .... It depends on how important speed is to you. I don't think this USB job is any faster than the old one which was fast, but it is only an impression which I cannot prove one way or the other. Certainly its resolution and colour accuracy are better than anything I've tried before.
