If you're in the market for a big-screen television and I'm talking 42 inches and above then I'd suggest plasma as a safe bet. Plasmas give you more bang for your buck and while LCDs can give you better resolution, plasma still has the edge in terms of picture quality.
At the smaller end of things (17- to < 42-inch TVs), LCD is the only way to go if you want something slim and tasteful. And the best thing is that LCDs are getting cheaper all the time.
There has also been a lot of debate surrounding use in bright environments versus dark, cinema-like conditions. The traditional wisdom is that LCD performs better during the day due to its backlighting system, and that plasma works best in a dark environment, as it uses a glass front. Nonetheless, products like the non-reflective glass plasmas and LED-backlit LCD panels with their better blacks completely turn this logic on its head!
While these exceptions do exist, plasmas do generally perform better in the dark, but models with an anti-reflective coating such as the new Panasonic plasmas are the best all-rounders
I have a Panasonic 42inch Plasma and it's just awesome! Fantastic colors that are vivid and sharp with zero bleed in True High Definition! Far better than all the > 40 inch LCD/LED TVs I've checked out!
I strongly suggest you go in for a Panasonic > 42 inch plasma as they are the pioneers in plasma technology. But BEWARE! There is one downside to plasma TVs. They consume 200 - 250 watts of power! This may inflate your electricity bill by a few rupees. But take it from me - it's worth every dime you spend!
This one would cost you between Rs50k and 60k - well within your budget. So go ahead and take the plunge.
Cheers!
