Not so sure about that. (the plasma thing, not a comment on the previous post)
When I read up on things I got the impression that plasma was the `old` way to do things and LCD tech was doing the catching up, exceding in some cases.
A purchase on a scale of this, I read a load of review articles (like the OC3D - but for TVs) and sounded people out after I`d whittled it down to a handful of models. Toshiba seemed to have the better tech per buck, but Samsung undercut them whilst maintaining a second spot. Sony was just silly money for the same sort of thing.
Of course, now I`ve done the reading, I don`t have the linkage at hand >.<
