Fujitsu ScanSnap S1300i
If you're still looking for a scanner to go paperless with, be sure to add the Fujitsu ScanSnap S1300i Instant PDF Sheet-Fed Mobile Document Scanner to your list.
The $260 desktop scanner boasts fairly impressive speeds — the company promises grayscale and monochrome scan speeds of up to 12 double-sided pages per minute.
As opposed to my go-to scanner, the Doxie Go, the S1300i includes a 10-page Automatic Document Feeder that can automatically detect paper size, skew, and blank pages.
If the Snapscan series is past your budget, check out the S1300i. It looks mighty impressive.
