As others say, plasma offers a different experience in watching movies and there is no doubt in that. For similar experience in LCD, you have to pay a lot to buy the top end LCD models. Having said that, first you need to decide what your choice is between LCD vs Plasma. In case you have any confusion between Plasma and LCD, clear that first. There are so many threads (both in this forum and outside) on LCD vs Plasma. So first go through them and get convinced on what your choice is. Beware of some of the biased/thoughtless suggestions given by few fanatics. Once you are convinced for Plasma or LCD, here are my suggestions :-
1. If LCD is what your final preference is, go for 46 inch HX850 and as
just4kix pointed out, you may get a discount on that (final price might be around 1L or lesser than that). You can wait for 2013 Sony models, but I am afraid you may not get a 46 inch model for around 1L. One of the forum members got a huge discount on HX850.
2. In case you don't get HX850, then there are so many options from both Samsung and Sony. To me, EX650 is a good performer and equally good models are available in Samsung as well. So in that case, you better do an audition with your own video clips stored in your memory stick.
3. In case your choice is Plasma, there are many suggestions. You can get a 50 inch plasma around 1 L. Samsung is coming out with new plasma models for 2013. Panasonic is yet to release their 2013 model line up.
So first get to know the facts on LCD vs Plasma and choose your preference. I reapeat ... Don't get influenced by some of the negative things said about LCD vs Plasma. There are lots of unbiased opinion/suggestions on this. So once you become aware of the facts, it will be lot easy to finalize the exact model.
