I've been researching the Big screens for 3 months now. Price and quality being the main issues. DLP, (rear Projection) can be ok and have really cut down on the bulkiness. If you're after size and can sacrafice a bit of quality, DLP is down pricewise compared to LCD or Plasma. The main downside to the rear projection is the bulb will go anywhere from 6k hours of usage to 10k. They can cost as much as 3 bills to replace (bulb only). LCD has come a long way to compete with the quality of the Plasma. Their Blacks are better these days and they have come up with a way to help the action scenes from appearing "jumpy" by boosting the rate to 120 hz vs. 60 hz in older units. Also, they are imune from the "burn in" factor which can hamper a Plasma. Things like ticker screens running at the bottom of a news channel can cause burn in after a certain period of time. LCD's have also come out with a greater angle of viewing without darkening the screen. LCD's also tend to be brighter and easier to see in bright rooms. Plasma still has issues in this area. Talk to any professional in the business and they will tell you that a good Plasma is much better than any other style. Plasma has been King for a few years now, but the LCD has become quite competative.
Now for quality, 1080p is currently the lastest and greatest format. It has twice the refresh rate than the 720p and is also better than the 1080i which only scans every other line when processing the picture.
BluRay and HD Discs are in 1080p. It looks as if Bluray is going to win the format war and HD might go the way of Sony Beta.
The Specs, if you are buying anything over 42", I would definately suggest going with a set that is 1920 x 1080 Display resolution. This is the latest technology in resolution. It will give you an overall clearer picture on whatever you are watching. I read a CR review that said a lower resolution is ok for the 40" and below, which can save someone some money as last years models were quite a bit lower.
Another thing to look at is the contrast ratio. It can help you recieve a clearer picture as well. The higher the ratio, the mo gooder it is.
I ordered a 47" Toshiba LCD on Monday, the price I got it for was $1,399, no tax, free shipping. All the latest and greatest bells and whistles too. I consider the 46" Bravia strongly, and looked at both sets at Best Buy side by side. The Bravia was a tad clearer picture wise than the Toshiba Regza. The Best Buy rep said the Toshiba could be adjusted to a better clarity. The price of the Bravia was $2,199. The Toshiba was $2,199. I asked the rep if they could match an online price I found for the Toshiba and he said the best they could do is knock it down to $1,700. I went home, searched the 46" Bravia, the 47" Toshiba, the 46" Sharp Aquos, and several others in the same size range.
You must be sure to compare Display Resolution while comparing prices. The lower Display Resolutions have really come down in price, but some are still out there slightly below original retail. Be carefull NOT to leap into a buy until you have made all the comparisons you can.
Here is a link to the place I ordered the Toshiba from. The next morning after I ordered it, the price jumped up to what it is currently listed.
Good luck, and prepare to have some aspirin handy, as well as moving a finger between you upper and lower lips repetatively. (don't forgot to make the noise too) Good luck, your best deals will be found online with no shipping or tax if you can be patient enough to wait. Circuit City has a tendancy to advertise a product available for local pickup online, then as soon as you try to order it, it is no longer in stock, OR availble online either. You can spend your wheels trying to deal with them.
I truly wish you luck!

Oh, I forgot that a Best Buy rep told me that Panasonics tend to have issues after 1st year, Online I found horror stories about the Olevias. And, that CR reported that the Westinghouse brand was a good choice, steady, quality and pricewise.
