Place in Chicago that rehabs/converts Rolands. They add heaters etc... Can't remember the name though. Rayco and SignSupply in Chicago have demos/refurbs.
Sign Outlet Store in Chicago -
Digitsmith.com, GlobalGarage.com, are good places - but I would prefer a place that refurbs that way you know what your getting
I can't help noticing most of the printers on Digitsmith.com were Roland, and there were very few Mimaki printers... I wonder why?
Probably because there are more of them sold than all the others combined.
