I use one mostly for commercial (IE - desktop publishing) output rather than artistic output, but if you have a chance, take a look at the Xerox Phaser printers. Very expensive printers - "desktop" models start around $5,000 by the time you add sales taxes & extra inks, but the output is superb.
Based on wax ink blocks, it has a look unlike anything else I've seen. I very seldom see them for art prints, because they are aimed at the business market, and they are used for outputting hundreds if not thousands of copies per month.
But if you can ever take a look , please do. I love my Phaser.
