Howdy, As per Adam Barratt's review on the Panasonic AE500E Projector I have chosen this for my projection unit. However Im having trouble picking out a screen to display it on, I borrowed a projector from the office for the weekend to test out designs for my HT Room, The throw distance is going to be about 4.7m. When it is displayed its just alittle bigger then 100inch. Im just wondering are there many diffrent types of finishes on the projector screens? diffrent crystals? which are the good ones to go for etc..?
