I would go with the graphtec, but i would go up to the FC 8600 series. If your going to do a lot of perf cutting I think you will be happier with it.
My 2nd pick would be the summa.
I would not pick the Roland, I am not a Roland hater... we own multipal Roland printers and printer/cutters as well as engravers and have been very happy with them all. Just perf cutting IMO is not Roland's strong suite. Their plotters added perf cutting after the fact, where as the graphtec was built to do that from the start.
