Availability & quality of flatbed scanners

My wife has some artwork that she would like to digitize so she can distribute prints instead of originals. She needs relatively low resolutions of ~300 dpi for web postings and at least 1200 dpi scans for print making. I have a ten year old HP 3750 scanner attached to a Win7 workstation that I use for occasionally scanning documents and pictures. I would prefer to have a scanner attached to my wife's Win10 workstation to eliminate file transfers between the workstations, retire the Win7 workstation and hopefully get better quality scans. When I started looking for scanners with Win10 drivers I found a lot of all-in-one printers or sheet feed scanners that I don't want and some very high end commercial scanners with attendant high price tags. I was hoping to find a plain flatbed scanner without a sheet feeder for under $200 if possible.

Does anyone have experience with flatbed scanning in the Win10 environment? Is there a cost effective method of generating quality scans with a Win10 workstation? Will the quality be sufficiently better than my old 3750 to justify the expense? If I stick with Win7, is there a better quality scanner, perhaps a commercial model, that I might find used on ebay?

regards,
George
