+1 for the Scansnap.
I was planning to scan reams of documents with my manual feed flatbed scanner, and never got around to starting. Two months after I bought a ScanSnap, I was done with the job. It cost a couple hundred bucks, but it made a huge psychological difference to have the right tool, and saved a bundle of time as well. CAVEAT: we are already FI, and the ScanSnap scarcely made a dent in the budget. If you are still paying off debt, consider looking for one used, or borrow one.
