I really wish someone would start producing something like this commercially - seems to me a natural kickstarter type venture. The light-source would need to be something more compact - possibly a flat LED panel - and the film would also need to be positioned in a holder that could slide and click effortlessly into place. But in almost every way this is an easier venture than creating a new scanner - which another forum member is making a heroic effort to do (and doing a great job so far, I should add!)
