Your best bet in my humble opinion is Quadriscan, ( [ www.quadriscan.com ] , 6000 Saint-Urbain ) if you're in the Montreal area, they can do a very good digital output, which is what you'll be going for, being that for offset, yes the usual quantities are 500/1000 minimum... they had good prices last time, and they treat with small-timers such as ourselves ((-_-))
