I have a subscription pinball repair site located at
http://www.pinballninja.com and the site includes almost 800 game specific repairs, which are categorized in a table of contents for easy searching. Also there's nearly 300 HD videos on pinball repair there too, inside the repair blogs.
To get a user-id normally a $20 or greater donation via paypal (as described at http://www.pinrepair.com/donate ) is required. But until the end of July 4th, a $15 paypal donation is all that is required to gain access to the site.
Thank you and please feel free to email me with any questions.
