I only do 8 or 12 sheets a week, and I still do them in trays. It's cheap, reliable, fast, and cheap. I don't know what all the fuss is about with scratches and stuff -- never had them -- and figure most of the other gizmos mentioned above need to be loaded and unloaded, which might cause scratches. If you are doing vast numbers and/or you don't have a darkroom, well, yes, but if it's a casual thing, there's no shame in doing the tried and true.
