Thanks for the link Thomas, like Evind's super8databse, it is a very good and informative group of articles. This link would be worth adding to the the super8database for anyone who wanted to get into hobby and find a meaningful article on projectors rather than look at some fanatical forum collectors on various platforms who, in many cases, believe only THEIR projectors are worthy.
It would be a good addition to the already excellent projector's tab on the database. An awful lot of work has gone into it by those who look after it. For anyone who still hasn't looked, your missing out. This link is just one tiny part of the database which is constantly being added to.
