I've been using a Roland Camm-1 cutter for almost 8 years now, and it is a work horse. Using Illustrator with a Cut Studio plugin, and I can do up to 23" at a go. I get most of my vinyl through SignWarehouse, and their service has been excellent. As Robin mentioned, weeding can be time consuming, and has a small learning curve, but we do everything from large signs to multi-paragraph didactic panels in vinyl, and it saves us a ton of money, plus, you can edit/change down to the wire. Not that any curators we know would ever re-write at the last minute!

Contact me via message here if you have any questions.
