So a while back I read about there being some issues with graphtec ce7000 unit. I need to pull the plug on a new cutter, but I don't know if I want to commit to problems. I am asking here, because I feel it's where I can get the most honest answers from actual users of this machine. What do you think would be a better buy? A new ce7000-60 or a refurbished demo model ce6000-60. Or something else in the same budget. I use my cutter almost daily, so it's got to be reliable. Thanks in advance.
