Fortunately, it is not that hard to find a good scanner.
Anyone in need of an entry-level one should take a look at the Epson DS-1630.
While the scanner is definitely not the fastest one, it has the right features for low-volume scanning needs.

1500 pages a day is the maximum number of pages that the scanner can scan.
Scanning more will only increase the risk of damaging it.
Top speed is 25 pages per minute or 10 images per minute.

The latter is the speed measurement for duplex scanning where an image represents one side of a scanned document.
The scan speed for double-sided pages is quite sluggish.
Anyone whod like a scanner that can scan double-sided pages in a single pass should consider buying another one.

For example, take a look at the Epson Document Capture Pro.
There is Abby FineReader too, a dedicated software to recognize and convert the text into editable text.
