I know this question is old, but thought I would respond; Although I’m afraid my help will be limited. I have both machines, and love each one. I tend to use my plus machine for anything that fits through it where I can use my magnetic platform or any steel die that fits. However the Pro machine is easier to turn the handle on. ( Just my opinion) I believe because the machine is much heavier and takes less effort because it’s more stable. If you have the budget for just one machine and room for just one machine, get the Pro. It is a much larger machine and requires a dedicated space to keep it. The Plus machine is just like the regular size, and yet it has a wider area. Some of the envelope dies such as tattered lace work better with the Pro machine. If you think you will ever want the larger size dies, go with the pro. I use that for larger projects and for the dies for boxes and envelopes. I do have stepper dies that do fit into the plus machine, but you cannot angle them. I started with the plus, then bought the pro. I’m keeping both, as the plates are interchangeable and I like the Pro for the larger steel dies. Depends on your budget and space. The pro, again, is much larger and heavier.
