I've been using scanners since they first came on the market as a dreadfull hand unit, but we though it was great. Since then, been through about five or more. My latest is a Canon 8000F which is quick and fault free. It produces perfect reproductions every time but I know it's a bit expensive. Looking through the specs of Canon, I note that the 5000F is virtually the same apart from the facility of scanning blocks of 35mm transparencies.
