Well.. before LCD's caught up to Plasma in terms of black level, it was a choice of "You need to avoid burn-in" or "You want the best picture".
Now, at least from what I've seen with the new Sammy's, it's damn hard for me to recommend a plasma, unless you are a black level fanatic (which plasma still has the best black levels at this point in time) or hate dead/stuck LCD pixels (like me).
LCD has just improved so much in so little time; a year ago or longer, I would have laughed at the thought of LCD TV's, because Plasma was where PQ was at, hands down.
The best part; LCD does not burn in. If you get an LCD with LED backlighting, the brightness and contrast ratio should stay rather consistent over the life of the set.
But hey, I have no problem with plasma set's at all. Kuro's and Pannys look just as great as the Samsung or LG LCD's.
As far as LCD brands (in no particular order)
Samsung
LG
Sharp (they at one point were makers of all kinds of LCD panels for other companies)
Sony
It's a pretty safe bet with any of those guys. Out of the list, I would probably venture to say that Samsung is probably the first one to break... but I've had quite a few encounters and experiences with Samsung sets, and they work longer than a Mitsu WD-57732
