I have the 15" model. At times, I wish I had gone 28", but space was a concern at the time of purchase. So far, the 15" has done everything I've needed. Before I bought it, I had considered the Cricut or Cameo, but, they seemed too light for my needs and plans for the future. They could only handle cut sheets, 10" vinyl which would have been very limiting. Now, 4 years later, they have changed and I believe roll feeds are available. I'm semi-retired and I don't advertise. Word of mouth keeps me busy enough. My cutter & heat press have paid for themselves. When I bought them, that was the goal. Think about your needs, if you are planning on commercial applications, go bigger, if it's for personal use, no need to go for a big ass Roland or Graphtec. Your budget, needs & plans should guide your purchase...
