I have a black and white Samsung laser (SCX-3200) that just went and went. It's in the garage. USB only, generic PS and PCL emulation, $5 refill kit available where the only gotcha was you need a chip that always reads full.
I was really disappointed when HP took their printers over.
We replaced it with a color laser (Canon MF632Cdw) because my wife wanted to print sewing patterns, and I'm not near as impressed with it. No real problems, though, other than the mess that seems to be UFR II on Linux.
