Please help! As some of you might be aware I'm very attached to my Trinitron Wega flat display which i've now had for approx 6 years. I'm very tempted at the moment however to take the plunge and buy a Bravia V4500 in the sales as there are some very good deals around. Is it really worth my while? I watch (and will continue to do so for some time) standard definition. My Trinitron is still producing wonderfully sharp, vivid pictures but i'm not sure on the lifespan of CRT - i've heard 8-10 years normal use is the standard. Another aspect of LCD tvs that concerns is the sound quality...i'm not too keen to buy extra speakers at the moment and the Trinitron (due to its depth!!) has an inbuilt bass unit. Some honest opinions would be much appreciated!
