Just saw the KDL-52V5100 selling for $1700 at BB today which is priced lower than I've seen. Been thinking about replacing my DLP for some time now. Any thoughts or recommendations?

What is a "PC input"? Is that ethernet connection?

I watch a little football during the season so I'm hoping the 120mhz will cut the mustard...
