I looked at many machines before I bought my 1100. I can't comment about the Roland. But I can tell you that the Tormach has been a wonderful machine. But beyond that is the company itself. They are superb at support (both on the machine and software). They continue to upgrade and maintain their machines. Pathpilot, their new open source machine controller software, is a great example. It's so much better than Mach 3 and continues to be refined. I'm very happy with it, and I was able to get the machine, 4th axis and a pile of tooling for a very reasonable cost.
