Buying new TV’s now days is kind of like a chevy vs ford debate. It is really personal preference. They are all good if you go with a high quality unit. It really comes down to how much money you want to spend and what is on sale at the time in my mind. Now for my opinions.
LCD or DLP- I guess the main question is do you want to be able to hang the Tv on the wall like a picture?? or is it going to sit on a stand??. If you want to hang it you either have to go with lcd or plasma.
As far as picture goes unless you have a very high components and cables you will not notice much difference between two comparable units. What I am saying is comparing 1080i to 1080i.
Reliablity- Both Lcd’s and Dlp’s have had some issues in the past. They seem to be getting these straightened out. Lcds have been known for having power supply boxes that fry thus leaving you with a televsion you cannot watch because you can’t turn it on. Other than that Lcd’s tend to run a little hot at times thus causing some problems. Dlp’s on the other hand run into the same power source issue at times. Not often but I have heard of it happening. Dlp also runs off of a light bulb source and a series of mirrors. Over the course of time the bulbs burn out. Usually between 2-5 years from purchase depending on use. However I have heard of cases where they go bad 3 months down the road. This is something that you will alwas have to deal with. Replacing bulbs is part of owning a dlp tv. However that is also the only real thing that goes wrong with them . If you continue to replace the bulbs you will have a tv that lasts a very long time.
I have had great luck with a Sony Lcd as well as a Samsung DLP. Now that the hd tv market has been saturated with other players there are alot of really good lower price lcd’s out there. A couple being Viewsonic and Vizio. Viewsonic has been making flat pannel computer monitors for many years. My cousin has had a 32 inch Lcd from them for 3 years with no problems and it has just as good of a picture as my grandfathers 32 inch Samsung Lcd. I believe the Viewsonic was in the 1000 range where the samsung was more like 2000. Vizio is also a great choice because the have been making components for alot of the big name tv manufactures for a long time. They recently started manufacuring the full sets and I think are making a nice product for the money.
That was alot of info but I know TV shopping can be confusing I hope it helped some rather than just confuse you more. Here is a great website for info on HD tv’s http://www.cnet.com/4520-7874_1-5102926-1.html
