Thanks!

Pre-purchase investigations... It looks like the SC2 pen holder is made to hold standard ball point pen refills. Is that right? I presume that two parts screw together, applying pressure to keep it in place? I ask because I'm hoping to use this to both pen plot and to crease paper. I'm thinking a steel "pen" like Cricut have could be used to crease. Also, I have access to some old (if they aren't dried out) HP plotter pens. Any idea if these will fit (or can be easily made to fit) into an SC2?
