hi all, i sold my outdated samsung 50' 720p plasma and am ready to move up to 1080p. My budget is around $1K-$1500. I found a local guy that have a 2010 55" Samsung LED 3D 55C9000 for a $1K. I dont care for the 3D capabilities. I typically watch sports and movies. This seems like a great deal considering the massive reduction on MSRP. Should i buy the current production model D6000? or C9000?
