I'm a bit too familar with printing technology (friend has printing shop), and basically must echo most of what gene said. Color laser printers are decently fast (esp. on multiple copies of the same thing), but their color quality SUCKS! The one exception to this that I have seen is the Xerox DocuColor 40, but it is a 40ppm behemoth with a 5 digit price tag. Current ink jet printers have print quality better than most dye sublimation machines, and at a better price, the only downside is high ink costs and the fact that most ink jet ink is water soluble.
I personally also agree with gene on the printer brand: Epson. You just need to find an Epson that fits your needs.
