yeh, so far I am finding that no-one can find a hand scanner that is very large at all.
I am also finding that people are still using photos and then preparing artwork from blown up photos etc.

To date, I have seen one commercial seller in QLD consistently reproduce quite good cabinet artwork for quite a few dmd machines using photography plus stretched/manipulated artwork etc, but the cost and time consuming effort has been expensive to him, even though he is using someone who charges a small amount per hour.

I have found one company who reckons if i take the pinball machine to their place of business, they can take photos using their 2011 year model equipment, and reproduce artwork at a very reasonable price with their state of the art latest software. Just got to find the time to take the machine up. Probably the best idea i have found to date.
