I've had an HL-s5687w for a year and while I've loved the picture I have had some issues and Samsung is replacing my set with a new 2007 HL-T5676S, the specs look great and I love the 120hz refresh rate, should be even better! Kudos to Samsung for taking care of me! Specs here...

I expect the new set in my home in about 3 weeks, will post my thoughts once it gets here.
