The higher the contrast ratio of the screen, the better the color intensity on the LCD or Plasma. You get away with anything 800:1 and up and still have a great picture. Plasma's contrast ratios will be in the 10,000 and up range. But you are comparing apples to oranges there. This is something that manufactures really try and promote, but it's not as important as other features on LCDs.
Also, Stunner, search the forums on the site for credit cards. There is a thread that lists the best credit cards available and which ones have the best deals going on. No interest, free money, rewards, etc. It's always updated too. The guys will also mention who to stay away from and relay some of their experiences to others.
