and I bought the KDS55A2000. Reason, facts, since 95% of all programming is SD:

Mosquito noise = nod to Sony, there is none.
Screen Door Effect = nod to sony, there is none.
Pixelazation = nod to Sony, least of all brands.
Rainbow/Halo effect = nod to Sony, there is none.
Moving parts = Sony has none.
HD programming looks like film on a Sony.

You really need to look at SD programming before you decide. No one will tell you this for a reason. They want you to see the HD results. You need to see what you'll be watching 90% of the time.
