DLP vs Plasma/LCD

I was just about ready to plunk down $4k for a Panasonic 42" plasma. I was at my brother's tonight watching the Olympics on his 42" Pioneer plasma (HD transmission,) when he tells me that I should go with a DLP for my bedroom, rather than the plasma. He claims the picture is much better and they cost less. I wasn't even considering a DLP because I didn't think it would fit in my bedroom. (being to deep) He says they make some, now, that are only a few inches deeper/wider than a plasma. Any takers? Is the DLP the way to go? If so, can anyone recommend one with killer picture quality, and relatively thin? thanks in advance. warren
