the speed issue of this argument makes no sense, if the originals of are such low resolution then the dpi setting on the scanner can be turned down and the scans will be very fast.

This thread devolved rapidly unfortunately. I've seen thousands of drugstore prints from the 1930s, 40s and 50s, which is the topic of discussion, and they very rarely rose above the level of mediocre quality. In this situation, the scanner isn't going to give a better job than a camera, or if it does, it's going to be marginal. The time factor just isn't worth it compared to being able to slap them past a copystand mounted DSLR for what will be no practical gain in quality. Been there, done it myself.
