Researching scanners is pretty frustrating. There is no standard for specifications, hardly any reviews, and nobody is using them to scan magazines. Theres very little difference between many models and even between multiple generations from what I've read. There is a consensus that CCD is better but you'll see manufacturers publish papers stating that CIS is superior. Probably because its cheaper and smaller. I have no idea if the newest scanners today which are mostly CIS are superior to a CCD from ten years ago. I have my doubts.
My recommendation would be to try and obtain scanners through government and institutional surplus. Prices can be more reasonable but you have to keep an eye out for the condition of the scanner which can be difficult especially if its not local to you.
If anyone is interested I thought I'd share a spreadsheet I made about ADF, A3, and A4 scanner models (mostly Fujitsu) from my own personal research. Not sure if its of any use but feel free to use it however you like.
