Panasonic TH-42PX60U Plasma or Samsung HL-S4676S DLP?  

I posted this in the RPTV forum but got no replies, so I thought I'd try here. Anyway, I'm trying to decide between the Samsung HL-S4676S DLP or Panasonic TH-42PX60U Plasma. After some research in both sections, it seems as if the Pan. plasma and Sam. DLP are the best options in my price range ( < $1500) and size range (40" - 50") as well. I also play a lot of XBOX 360 and I've heard great things about the Samsung not lagging at all. Also, it's great how the new color wheel hardly produces 'rainbows' and such. I was just looking to get some feedback and thoughts on these TVs, since I'll be heading to Best Buy or Circuit City later on. Thanks in advance!
