I would definitely recommend you get a smart all-in-one, meaning a professional-grade all-in-one that's a copy machine, a scanner and a printer. The reason is this: you can buy a dedicated scanner, even one with ADF and you end up spending quite a bit on scanning the items, converting, etc. We have such a smart all-in-one (Kyocera FS-1118 MFP, not cheap, but good) that scans to pdf. You can choose that it either stores those pdfs on an ftp share or sends them by e-mail. I prefer to have them sent by e-mail. The procedure is literally as quick as copying. Plus, the files I get are very, very small (about 30k/page for regular text documents). I scan most of my notes and store them on my computer.
