I have an Epson Home Cinema 1080UB. My room is 11'7" x14'4". I am looking at buying a 120" screen. Since we're currently buying a house, cost is a factor, so I found these two screens. I'd love to hear from people who have experience with one or the other or both. What are the advantages? disadvantages? What is the quality of the screen material? How often does vapex have sales/discounts?
