For my own tuppence worth I am still using my BV8-32 and 6-26 linked and picture quality is really good - however I got itchy feet when I saw my friends Samsung which knocked both out of court - so I borrowed a projector - definitely the way to go (for me anyway), a fraction of the cost of a new TV, easily upgradable, takes up no space and the fact that my B&O is all linked up means I can watch a massive screen in between the Penta Speakers with the sound and control of Apple TV routed through a BM6500 - sound and picture are excellent - I should add for movies which is 95% of what I watch. later I'll reuse my lintronic box to control a motorised screen and the projector - so everything is controlled via a Beo4. Big screen, big sound, small footprint - ok, not Dolby whatever and maybe not as sharp as a newer Beovision, but a great experience every time.
I suppose in some ways it depends on how often you watch TV and what you watch - a BV5 maybe fine for someone that has a large room and wants a beautiful looking TV and watches say the news or current affairs programs - not so good, for someone that wants High Definition and watches a lot of TV or films etc. The good thing is that there are real bargains out there to be had if you have a use for them -spare room, kitchen, study etc
