I mainly do 20x24 contract prints in b&w. But only have an iphone to take images of them to submit to shows. They do not look very good - only a suggestion of the contract print. I assume scanning the photos would be pricey so I thought it was time to buy a digital camera to take images of my analog work.

My thought was that a used, "obsolete" digital camera would be all that I would need to take close up images of my prints. Any suggestions for a make and model of digital camera that would be just good enough for what I want to do?
