I'm actually tempted by one
A long time ago, i managed to pick up and end of line proffessional quality HP inkjet, and have been reasonably happy with it over the years (xp64/vista drivers aside).
However, as i print fairly infrequently, i tend to find a lot of the time when i do need it, i need to run through lengthy cleaning cycles, or buy new ink, just to get it to work reasonably. Rather than print speed, the shelf life of the toner is what draws me. I do wonder about replacing it though, as the model i looked at, a full toner set cost nearly twice as much as the printer (with its half/quarter filed ones)
