Every once in a while, I get lured by enthusiastic descriptions and positive consumer reviews to look at less expensive photo scanners that are sold by lots of places, even B and H Photo. I recently bought one for about $60 that sounded like it might be a middle of the road solution. It was much faster than my Nikon and Epson and examples of scans shown on websites looked pretty good.
So, today, when I received this new low cost unit, I plugged it in and scanned four random slides from the mix I get from my customers -- i.e., slides that are what ordinary people take -- and scanned them with all three scanners.
