rpasta,

The C6300 is the 2010 model, and the C6000 is the 2009 model, so there are significant differences in the panel quality - and that's where most of the difference will be. Both are Edge-Lit panels, and the B model boasts a 1M:1 dynamic contrast ratio, and the C model has a 4m:1 dynamic contrast ratio. So the picture should appear significantly improved.

That said, if you can't tell the difference between the picture quality on the two, then do what's best for you and don't pay for a difference you don't see.

If you're looking for the Samsung Apps or Widgets, neither model will have them on board, but these are features that are also available on our 2010 models of Blu-Ray players, so you're not out either way if you decide to go that route.

You can find more information on those here:

If I can answer any other questions, feel free to let me know.
