i second the Z52, i've used mine for photo printing, but not with the photo specific ink, and the look like they where proffesionally printed, but they did fade, i've kept some from a friends wedding, for under a year, under cover, and it is begining to get noticable.
I bet if I had printed them with the photo ink, it might have lasted longer. It's zippy, and the black is good too. only prob I had was my roomate dropped a screwdriver into the paper in tray, but it came out lickity split.
Also it doesn't like to be shared over a network, no matter what the driver, or cable combo, it was an unknown issue till I had to call lexmark.
