I've done both slide and negative scanning with a DSLR - with a fairly "ghetto" setup, essentially a macro lens, a basic macro focusing rail, a slide holder and a speedlite for back light. I must say that once I nailed the focusing and diffused the light properly (spent a few rainy evenings with various attempts) it worked very well, and the quality and resolution were top notch. With a slide holder with multiple slides you can get through a lot of shots very quickly, quite a bit faster than a dedicated film scanner.
