I think I've narrowed it to these two which seem to be basically the same except for the size and the frame.
I have a dedicated room that is pitch dark with all the lights out. I think a grey screen is what I need, but someone please correct me if I'm wrong or feel free to offer alternative choices in the same price range, ie <$400.
I currently have a homemade screen made from blackout cloth. It has served me well, but it's time to see what improvement I get out of a "real" screen. Since the homemade version was only $35, the improvement needs to be pretty substantial...especially since my wife thinks it's ridiculous to make this purchase.
I guess I could add that the alternative is keeping my current screen and picking up a new turntable. I have my eye on a Rega P1 unless I can find a better deal used.
