Haven't really be following TV tech so can't really pick a good deal when it comes to TVs. We're looking for something around 50", with smooth motion (100hz?).

At the moment we're tossing up between these two:

Panasonic TH-50A430Z
LG 50LB820



Any input would be much appreciated!

Edit: should probably mention both of these are around $800 at dick smith/jb
