Hi smiley man,
I have had the ET1 for just over 2 wks now, but until lastnight hadn't really had time to use for any lenght. Just tested it when it was delivered. Been trying to get the loft ready for it.
Anyway i set it up with a 6ft screen (black out material wrapped around a 1.8 x 0.9 sheet of plasterboard resting on the back of a sofa

) worked very well actually. I have enough material to have a 100" screen in the loft & a 72" for downstairs in the living room (only cost £20). Well lets just say the for the £365 i paid for the ET1 that its simply awsome, i paid twice that for my 32" TV 18 mths ago.
I set it up for a session of Hi-Def gaming on my Xbox (just got the hi-def kit). I played Doom 3, NFSU & Soul Calibur 2 (just amazing the difference the hi-def kit made) i also tested some dvd's (Fellowship, Two Towers & Ice Age) & watched 1 of my favorites Jurassic Park (on the Xbox).
The pj was about 5 - 6 ft from the screen with me sat 9ft from the screen. Screen door was there but its really not a problem. Can't wait to get the loft finished to see if it can do 100"(will be sitting further back) at the same quality as the 72". Worth every penny, so glad i got it.
For the money you will NOT be disappointed.
I was going to take some pics but the batteries in my camera needed charging. If you like i can take some tonight ?
