Hello, I accidently bought a 50 inch plasma thinking it was an LCD. Its is an samsung FPT5084.

Full specs can be found here:

So, I wanted to return it because it was a plasma, and my friends tell me plasma's are great but they dont last as long. So should I go for an LCD screen. It was a bit expensive, here is my current setup and my soon to be, if I return it and get an LCD screen.

Purchase 1 (Boscovs):
1. Samsung 50" FPT5084 / $1999 + TAX
2. 5YR Warranty / 389 + Tax
TOTAL: $2505.16
-DOES NOT HAVE HOME THEATER SYSTEM!

Soon To Purchase (Amazon):
1. Samsung 46" LNT4665F / $1999 NO TAX
2. 4YR Warranty / $279.99 NO TAX
3. Samsung 5.1 HT-TX75 DVD Home Theater System / $379.99 NO TAX
TOTAL: $2659.97
-INCLUDES HOME THEATER SYSTEM

Also, both the TV's have the new 120Hz built in, and the soon to purchase has an extra 5000 contrast ratio, compared to the one I just purchased (15000:1 / 20000:1).

So should I return it and get a an LCD that will have a beter contrast ratio and a HOME THEATER SYSTEM! which is only 4 inches lower.
