We like the LN32D550 so much, I just bought a LN46D550 for our living room. It was on sale at BestBuy at $90 off. Signing up for a BestBuy credit card (no annual fee) gets a $20 flat rate discount off the first purchase over $50. So we ended up with a $110 discount.
Love the fact that the LNxxD550 series has two combo "component/composite" video inputs, the analog audio output, two USB ports and the ethernet port. (aside from the 4 HDMI input ports) A later LED model that I looked at only has a plug-in dongle for one component input which minimizes flexibility. Some sets don't have analog audio out to easily attach headphones. Seems that component & composite inputs are going away so it's a good time to buy now if those inputs are important to the buyer. The D550 series appears to be one of the last models with a lot of ports.
