Is the Sony VPS-HU70W projector screen any good? I was after a floor standing projector screen (not a tripod one) but didnt really want to spend too much on it, maybe £200-£300. The Sony is only £130 and I dont know what Id get for that. The other floor standing screens Ive seen, such as the Bretford Harrier and the ones here are all a bit out of my price range. Would to Sony be alright (for use with a PT-AE100) and if not is there anyting else in the £200-£300 mark I could consider? Thanks for your help.
