I have been considering replacing our (dying) 40" Samsung. Not needing 3D and after considering a few other factors, it seems the 55" Samsung 6300 is the set I have decided on. Over the past few weeks, I have seen the set as low as $899 (Black Friday week) to as high as $1199 (just $100 less than retail). Right now Best Buy has it for $1099 but I found an open box available for less than $850. It is missing the manuals but that isn't too big a deal. Are there any issues with this set that I need to be aware of?
