Done and Done. I have both my LP and Graphtec running in SBE via Parallels. I can also have the Graphtec cut straight from the Mac side too.
Depending on what your budget is - I'd go Graphtec. It took me years to want to put more money into another cutter, especially since my LP was chugging along just fine, but WOW! What a HUGE difference. Now the LP is collecting dust and never gets to see the light day. If you can't afford a new Graphtec, then find a working used one!
