I have a sony trinitron 27inch its about 10 years old, best tv i've ever had! I'd like to upgrade but i'm am totally behind in the televion world. From what I understand ( sony has ). tube tvs, plasma, xbr , projection tvs and hdtv. I have no idea how to deferenciate these. I would want to get a fairly big tv 30 inches and up. something that will be futureproof, I have about 2500 canadian to spend, so any suggestions?!! Thanks in advance.
