scanning microfiche

Brian Knittel and I have a few hundred fiche of IBM documentation and code relating to the 1130 (http://ibm1130.org). This is tens of thousands of pages that we'd love to get into a digital form -- in particular we want to get a few fiche done FAST because Brian borrowed them from someone else who won an interesting set at auction recently. My attempts to scan them with an Epson 2450 Photo have been unsatisfactory, apparently mostly because of slight focus issues that only become apparent at the highest resolutions, and I've started to believe that we need to use a real microfiche scanner to do the job. Unfortunately they're way expensive, and I can't think of buying one ... and service bureaus charge by the page, about $.10 per page to be exact. We need a cheaper option. So ... does anyone know of a fiche scanner that occasionally sits unused, that we could use? Or, does anyone have any better ideas? Thanks, Norm Aleks
