Can somebody give the low down working cost on these three type of printers...I've had a roland inkjet for 10 years, so I know the cost of inkjet. However, I don't know how it compares to these other two. I'm looking to buy another machine, and the type of work I do (racecars....bling bling graphics) the thermal Summa DC5 looks interesting. It can put out mirrors, brushed mirror, and even flourescents. That could be very valuable to me company? Any help and info would greatly be appreciated
