we ended up going with a panasonic 50'' plasma - it only had 720 dpi but looked just as good as the insiginia tv that had 1020dpi polus wiht the plasma you dont need to worry about the hz.....we did some research and read that for sports watching plasma is better PLUS it was $100 cheaper for a bigger tv.
We also ended up getting:
the blue ray wifi dvd player as well so we can stream video off of netflix
a soundbar that simulates surround sound and has an ipod dock
a really nice stand that the tv mounts to up higher
pics will soon follow

The whole bill with protection plan and tax was $1600 AND Best Buy has no interest for 18 months if you use your best buy card and make the minimum payment each month so its like layaway but you get it now . We were very happy with our experience - bought it all at the Legacy Oaks location. If anyone is in the market for a new home system I would highly recommend it.
