For my GM screen, I use the Savage Worlds customizable screen, primarily because I like to make my own panels. They're pricey, but I've gotten almost 10 years out of mine, so I guess $30 isn't that bad? Just be sure to keep packing tape on hand for when the seams split.
I've made custom panels for the three games I most often run (Labyrinth Lord, Dungeon Crawl Classics, and Marvel Super Heroes). The links below are for these three sets of panels. The pages are in the order I put them in the screen (starting from left-most on the GM side, to right-most on the player side). For LL & Marvel, the center player side panel will be art based on the adventure. For the DCC screen, it's all art on the players' side.
