Hi Julie, it would kind of depend on what you're planning on cutting the most. If you primarily do cast and calendered vinyl, the speed of the EV375 is a big plus. The settings that are controlled from the software are helpful as well. If you tend to cut more difficult materials like reflective or sandblast stencil, the speed advantage evaporates. Then, are you cutting so much vinyl that the speed is a factor? If your current EnVision is running for half a day or more, you probably need the speed. You could probably get a GS or Gx 15 and a 30 inch Graphtec for about the same price as your EnVision, if you need sprockets for Edge output, but still need other cutting done as well. BTW, the Graphtec plotter can cut Edge graphics, if that's an attractive option for you too.
Good Luck,
