I sell Fujitsu Plasmas. What makes them special is their combination of the best black level and excellent scaling. They tend to make even the best mass market plasmas (Pioneer) look more "digitized" by comparison. The downside is that they are more expensive than just about anything else.
If you want the best, check out Fujitsu's new Aviamo series of 1080p plasmas.
BTW, T-Bone is right. LCD seems to be gaining in popularity every day despite some serious problems with black level and motion artifacts due to slow refresh. They have gotten better recently, but they have a long way to go.
