I find myself in need of a new color printer as my current deskjet recently died spectacularly, print cartridge exploded, but that's another story.

Anyway I'm looking for suggestions for a printer that can print (at least) 11x17 inch high resolution color images. I have a budget of about $3000 but might be able to save up more. Are Color Lasers better then InkJets? Which kind is more reliable? What kind of experiences have you had with them? What did cartridges or toner cost and how long did they last? How easy are they to repair or find replacement parts? Is the color reproduction accurate and rich? Did I miss any dire requirements for a digital graphic artist?

Thanks in advance for the help.
