I did a lot of research before I bought my Sharp Aquos 37" TV.
I was first looking at Samsung but I kept reading reviews that said the sound was bad, so I decided to look into technical reviews and I am glad I did.
I have watched football on my friends HDTV and everything in the background seemed to jump around. Upon reading reviews I found this was a result of a slow response time of the TV.
Another thing I looked at was screen life. To make a long story short all three pretty much said to satay away from Korean made TVs, and stay with Sony, Sharp, or Panosonic.
When we got the TV the set up was a bit of a pain in the bottom part of one's anatomy, but once we got through that I got to sit down and enjoy.
The clearness of the picture on this 1920x1080 is nothing short of amazing. The colors are deep and so crisp and clean.
I was watching indy racing and it was super. The background just flowed by with none of the jumping that I have seen in other TVs.
I stuck with a 37 inch because of size limitations and this worked out super.
When reading between LCD and Plasma I am glad I choose this unit as anything this small (if you call it small) will not get a true HDTV due to restrictions of the plasma performance.
All in all I would say that anyone looking for a great HDTV at a great price you can not go wrong.
The resolution and the fast response time along with the Sharp reputation for quality makes this set a perfect buy.
