Roland Versacamm vs. Summa DC4???

I am wondering what everyone's thoughts are on which printer/cutter is better for the both quality and money. I am ready to purchase a printer cutter and am currently looking at the Summa DC4 54" thermal.

My question's are: Which is better, thermal or ink? Roland or Summa? Or is there another printer cutter worth looking at? Would you go with a printer/cutter in one or a separate printer and cutter and laminator? Also, with the thermal printer do I still need a laminator?

I will be using the equipment for vinyl decals, magnets, signage and banners mostly. Any thoughts and experiences would be greatly appreciated!
