I'm looking to get a vintage plotter. I am not particular about what brand they are, so long as they are reasonably functional and not too spendy. If the pens are dried up it doesn't matter to me, I can work around that. I would prefer a flatbed model, especially the models made by Tandy, and if it's got a Centronix port then that's a big plus for me. I'm looking to spend around $50, plus shipping, to get one.
