Mia gave me 2 birthday presents today. The first was a dirty diper and the 2. was that i could go out and find myself a new tv on her mothers credit card

.
I have looked at the LG 42" Plasma MZ-42PZ45v tv cause its quite "cheap", but i have no experience with plasma tv's. Ive heard that the screen can "burn" if you leave them on for a long time.
1. does anyone have this model (LG 42" Plasma MZ-42PZ45v)?
2. Are plasma tv's any good?
3. Are there huge diffs in quality and or "generations"
4. should i wait for large lcd tvs to come down in price?
Im in no hurry but I do love new toys so i dont wanna wait to long

-edit- any good websites that reviews plasma's, lcd's and home cinema gear?
