I have no idea what this is for - is this for 40k? If it were for the RPG, that might be one thing, though it would also depend if it were for 2nd edition, the one my group played, or 3rd, which is too steep, even if we wanted to change from the 2nd edition system and rebuy everything - but still, twenty bucks. But from the looks of it, it's 40k, which I don't play.
Screens have always been of questionable value, to me personally - they do help present quick summaries of tables and info, but their other main purpose is a double-edged sword - the actual "screen" function - sure you can hide dice rolls from players, in case you need to "fudge" them, good or bad, to keep your players alive, or keep enemies alive, or let players make hits on enemies they didn't really manage, because you realize the enemies are just too tough... But do you *really* want to truly divide yourself from the players at the table, physically, with a screen?
I like being able to obscure dice rolls, and maybe the adventure I'm using, so the players can't see any pictures or maps, but other than that, I like a more open atmosphere, and the whole screen setup really puts up a very definite opaque "fence" or wall between the GM and the players, and I'm really not fond of the mindsets that breeds, on either side of the cardboard.
