I guess I'd reply by asking specifically what you mean by "value"?
If by terms you mean cost, probably not much until you implement video upconversion. And then theres the debate on what is a high enough Hz level for a High Def TV signal.
I've had both the H/K and the Yamaha and personally neither make a signal "better" in my mind. In fact, as meticulous as I am, I notice a signal degradation. It's just one more video component something has to pass through.
Now this is just my history. Perhaps with a line conditioner that would change. But I'd base my purchase on the sound, and not the video feature...personally. Good luck with what you decide.
