I currently own this tv a samsung 55 inch C8000. Probably a top of the line led not too long ago. Looks like I missed out on the panasonics that just went out of business but I am looking at buying a plasma to make my movies better now especially black levels at night. Now that I have a good surround sound system built I am trying to determine if I should wait and hold out for the next big thing or buy something like this the Samsung PN64F5500 64-Inch and save money for the next high end black performance tv. Would like some suggestions and if its even worth upgrading yet.
