I see so many of these in thrift stores, etc, for around $10-15, that I pay them no attention at all. They're not particularly interesting since deskjet printers will accept HPGL also. I don't see them with an assortment of pens, as I once did, so I'd say that's the weak link. What's more, the color deskjet printers, e.g. DJ550, etc, costing about the same as the plotters, print in color, accept HPGL, and are about 10x as fast, even though they're quite slow. Third-party pens are available in art and drafting supply houses. There's a line of refillable ink pens from Kohinoor which I've found doesn't work terribly well in my somewhat larger 7595B ("E"-size) plotter, but they may have something for the little desktop plotter. The not-refillable ones seem to work fine, though. If you use the roller ball pens or the tip-wicks, they may work for you. Good luck!
