I have the Epson Stylus Photo 750. The only problem I've seen with it is that it the ink jet heads tend to gum up if you leave the printer on for long periods of time without activity. So, just remember to turn off the printer when you are done with it, and the Epson's should be fine.

I've only used Epson ink, and am too chicken to try the 3rd party stuff.

Likewise for laser printers - stay away from recycled toner carts. Bad news all the way around.
