For the record, most of my scans come from a Fujitsu auto feed scanner. It's not the ScanSnap series, but the one above that. However, the ScanSnap scanners like the x1500 also do an excellent job. Of all the scanners I have used (two HPs, two Canons, Epson v600), the Fujitsu produces the most accurate scan when comparing it to the paper copy.
Debinding is the fastest and easiest way to scan something but it's the 100% destructive. The scanning service idea might be the way to go if you don't want to destroy your magazines.
