I just picked up a 46" Samsung 1080P LCD for about $1,300 last week with rebates etc. - retailed for 1650 a few weeks back and $2,100 a few months ago.
(Yeah, I know somepeople hate sam'junk' but I don't and the reviews on CNET/AVS forum were stellar.)

Prices have reached a good price point now IMO - decent technology for not bad price across the board.

Will they drop more? Undoubtedly yes, I paid over over $2G's for a 200MHz "top of the line" desktop about 10 yrs ago - how much would that be now even if you could buy it.

If you don't "need" it right now and a few $100 in savings is worth it rather than having it on the wall now then I would wait - prices on these are only going one way.
