I am looking to purchase a new tv soon, as my tv right now is a bit out of date. Now im hearing alot of things on plasmas, LCD, DLP, HDTV, all of that stuff, but i have no clue what each is. Could someone please help me tell the difference between plasmas, lcd, hdtv, etc... and what is the best right now. I know that plasmas have around 40k hours before the bulb burns out. What im looking for basically is a tv (40 to 50 inch range) with clear image quality, and that is hdtv ready as i will be getting directv in a few months. Thanks for the help guys.
