This query is as old as time itself.
I ventured into purchasing a new TV approx 3-4 yrs ago, and was befuddled as to which way to go ....... Plasma v LCD ??
I spent hours researching the different makes, models, etc etc ......... I also read lots of forums as well. The outcome ?? 50% preferred LCD, the other 50% preferred Plasma. It appears from them in the know, there's pro's and con's with both types.
I settled for a Panasonic Vierra 37" LCD. If memory serves,they'd only been on the market approx 6 months when I purchased one ?? Whatever, it's been great with no problems at all. Just another point though U UB, if you weren't already aware, don't just plump for the biggest screen that there is, there are reccommended viewing distances in relation to the size of screen that would be best suited. I say this because mey neighbour and good friend, Mr Gadget-head, had himeslf a 70-odd " TV and is the worst picture ever due to his seating being so near. Pixellated to hell !!!
Again, if memory serves (and mines awful), I think snadge (member on this forum) gave me some good pointers all them years back on the 'DSL Zone' forum. I think it was him ?? Good luck.
