Got a mate who has £1500 to spend on projector and screen. Ideally would like electric screen of about 5-6 foot. He has narrowed choice down to: Sanyo PLV_Z1 (offer price 1499.99 with electric owl screen) Epson-TW10 (with manual five foot screen £928.25) Sony VPL-HS2 £1174.95 (no screen) Are there any horror stories with any of these machines? Is there one to avoid etc. Any help much appreciated.
