Good tool, looking forward to more

There is a good range of pro projectors available here, but some glaring omissions, such as Sanyo, which is definitely a bread and butter brand for many pro/rentals. Would also like to see

The calculators and lenses seem accurate and very useful.

I would love to see the addition graphical, slider based, values for throw, size, etc other parameters, similar to the way projector centrals online calculators work. With a slider its easier to see where you need to be quickly. Also lock values and see what effect different lens choice will make

Keep up,the good work!
