Dragging up an old thread here, I'm entirely happy with my Samsung CLP-620. The thing is built like a tank, unlike my earlier cheapo Xerox/Samsung CLP-300. I have every reason to suspect that the CLP-620 will last for years to come. Among other things, it has a much better web interface that tells you what's going on with the printer.

It's also nice to be able to crank out 20 ppm in full color and duplex. I still don't print very much, but when I do, I don't generally like to wait around.
