Looking at the Samsung HLS5688W vs. the HLS5687W I am hard pressed to find a real difference between them, yet there is a $750 price difference with the 688 being more. To best compare, here is a link that does a good job. Hope the link works. http://www.onecall.com/ProductCompar...=31426%2c31428 Now honestly, what is the difference between them and does it justify and extra $750? Still battling back and forth in my mind and with my eyes on a DLP vs LCoS.
