I have an HP 4670 scanner.
As mentioned above, these scanners are ideal for scanning oversized plastics, playfields or even cabinets with ease.
I can't do "a couple of bucks" given what I paid for it (they are long since discontinued and fairly hard to find without paying a premium).
PM me if you are interested and we can discuss price.
Like this: (scanning lid is removable and can be laid flat on any surface).
