I love my Graphtec CE5000-60 and wouldn't go back to using anything less unless I had no other choice.
I moved at my "real job" from part-time at Water Pollution Control (fancy name for Sewage Treatment) to full-time at Public Works, which covers sewer maintenance, street repair, electrical, and street signs. I took a look in their cutting shop, and aside a hundred-zillion dollars worth of high-grade reflective vinyl, they have a Vinyl Express QE54, which is re-branded Graphtec cutter.
If it's good enough to do all the street signs and city government vehicles for an entire town, then isn't a Graphtec what you should be using in your shop?
