We've had an HP Designjet T1100ps plotter for about four years and have been very pleased with it. Quality and speed are excellent and so far we've had no maintenance issues. This model is discontinued, but the HP Designjet T1500 seems to be similar, albeit better.

Our applications are CAD/GIS, and we always plot from rolls of paper, so I can't comment on single-sheet ease of use.

We've had a Designjet T1100PS for almost 5 years, and are pretty happy with it. Our main use is CAD/GIS drawings, and we plot from paper rolls. I can't recall any maintenance issues, and the quality is great.
