All, I am tempted to get a Sony HS1 (quoted £1,975) but noticed some older true 16:9 Sony 400's being sold 2nd hand, which are, surely, higher spec. than the baby HS1. Which sould I buy? ( I have a dedicated 4m x 4m room. Pitch black.. it's a cellar. Low ceiling height, thought, at about 6ft 4"! ) Thanks!
