scanners (was 1/2" tape cleaner?)

Along the same line of sharing from AL, can you share with us what equipment you use to scan books, manuals, and papers in order to archive them on bitsavers? -- Primary scanner is a Ricoh IS520. B&W up to 400dpi, double sided, 30ppm, handles 11x17 sheets Built like tanks. I think we have a dozen of them now between Eric and I. Just found two on eBay for under $300 ea incl shipping. SW is windows-based and quirky, but after running a million or so pages through it you learn to get around the bugs. I made the decision a long time ago that the data on the pages was more important than the bindings, so bound docs and books are disassembled to scan. If I can find bound docs in poor condition (water damage, etc.) I'll use those first. I have a Mustek 11x17 flatbed SCSI scanner for large format or color scanning. I also have a Mekel M560 microfiche/aperture card scanner that I'm just getting up to speed on, and a couple of large format (36") scanners that I need to get going, and a bunch of 3M microfilm scanners in storage.
