Any Xerox solid ink.
Depends on your end use I guess. For interoffice crap and printing your emails it doesn't require much of a printer. For a broad range of print quality from interoffice stuff to photos/brochures from one machine a Xerox is hard to beat on a per page cost.
For 5-600 you can get a ColorQube 8570.

They sell refurbs too.
