We cannot and will not say nothing bad about Ordway - they seem to be very decent people. Look at the machine carefully. It is all over, and many starters and hobbyists have them. Ordway once used to market it with another name.
Basically, it is a stepper-driven machine. If you sincerely want to buy a plotter for the last time, look for a servo-driven machine and make sure that it is HP-GL compatible. If not, expect it to quit like the Stika, another entry-level stepper setup.
Hope this helps.
