I wasn't really looking for a photo print scanner, but when I saw the insane scanning speed of the Epson FastFoto FF-640, I knew I wanted it. The FF-640 can scan print photos as fast as 1 per second and allows for prints as long as 8.5"x120" (that's longer than most traditional lab prints).
The unit itself is $649 normally, but Amazon currently has this machine at $549.99.
Here are a few videos of the Epson FF-640 in action. Watch it go!
And yes, the scanner can scan documents as well.
