Jay Stafford is one of the key members of the IPDB, who helps to accrue images and documentation on pinball machines to post for reference.
The IPDB site provides an invaluable service to the collector community - I know, speaking for myself, that I would be absolutely lost without the availability of the images and information on the site.
