The best place to buy a Scantron machine is directly from the manufacturer, Scantron Corporation. It is also possible to buy used Scantron equipment from eBay and Craigslist; however, used machines do not come with warranties or service plans.
Scantron Corporation provides free demonstrations, product registration and consultations for purchases made through the manufacturer's website. The company also offers optional paid training and free online help for scanning machines. Scantron Corporation sells scoring machines based on output level. The low-volume, manually fed machines scan up to 2,800 pages an hour while automated, high-volume machines can scan up to 15,000 pages per hour.
