Chris,
If you look back a handful threads from mid-June, you'll find a couple threads debating on this exact subject -- though we weren't specifically considering the Series 6 plasma.

If you can wait for some price slashing, I'd suggest waiting as long as you can for the plasma. If not, the Series 7 LED DLP looked pretty good to me though, yeah, it has its caveats. Did you try looking in Circuit City? That's where I found one on display up here in the NYC area -- couldn't find it anywhere else.
