I had the Model B (i believe video spectra, it was 1.5 gain, i know that for sure) at my old house (building a new one) and I loved the screen itself.
However, I'm replacing it with a fixed screen (I had a pull down). If you have to get a pull down, get one that has the tension on teh sides. The screen itself was outstanding, but after a few months, it started to have waves in it. Really killed the picture in some scenes. I highly recommend a fixed screen.
Just my $.02
