Several newsletter readers have written recently to ask, "What is the best scanner?" As a single individual, I don't have the financial resources or the hours available to obtain one of each of the dozens of available scanners and then run side-by-side comparisons. However, one organization does have such resources: PCMAG.com
You can find an excellent collection of articles comparing nearly all of the general-purpose desktop scanners and multi-function printers/scanners available today at PCMAG's web site at http://www.pcmag.com/category2/0,2806,7497,00.asp
I do hope to continue writing about special-purpose scanners that should appeal to genealogists, however. I'll do that just as soon as I get back home and have some time available. (I flew from Florida to Utah this morning and am in a hotel room tonight in Salt Lake City.) I have written in the past about handheld battery-powered document scanners in Plus Edition articles and plan to write soon about a battery-powered scanner designed to copy both color and black-and-white snapshots.
