I found that an all-in-one was useless for scanning/photocopying without a feeder. And all the ones I saw were useless at feeding.
So I got a Fujitsu ScanSnap scanner. Very small footprint and you can load 5 or 6 pages.
Turns everything into PDFs, supports multi page scans and gives you some tools. Software a little weak, particularly with file names (I want my files to begin with YYYY-MM-DD and this cannot be done. YYYYMMDD is as close as it comes, so no big deal)
I'd recommend it for home or (very) small office.
