I've used a Neat scanner, which is similar to the Doxie. I can't imagine going paperless with a slow, manual scanner. Unless my life were a lot simpler than it is right now.

The ScanSnap seems to be universally praised for its speed and reliability, and a better bet if you can afford it.

I usually toss my old documents in sink filled with warm water and detergent. It turns them into slurry quickly enough, with no need for a shredder taking up space in my office.
