Pinnacle (Studio 2) has these pretty cool customizable GM screens. They are landscape screens so you'd have to create all the charts and things that fit landscape or learn to read sideways. I'm certainly thinking about these screens as you can swap them out and create screens for other Vajra games by just making and printing out the pages, which then you just insert into the screen itself. It also has pockets on the front and back so you can put GM stuff on one side and Player stuff on the other.
Pretty cool.
