For a properly extremely overbuilt plotter, you could do what I've done: tape a pen to a 3D printer. It's a bit like building a back massager by putting a cell phone on vibrate and texting it continuously, but it's also a dang good plotter once you figure out a set of G-Code instructions that don't destroy the pen by accident.
I've been thinking of taking advantage of the ability to raise the pen really high to do something crazy like use a quill and an inkwell, but I use a bed slinger printer, so figuring out an inkwell that doesn't splosh ink around everywhere or floats just over the bed is probably more work than the idea is worth.
