LG LB1, how does it compare?

Hi

I'm looking for info of regarding LG's 37LB1.

I will be using this set 70% of the time to watch movies directly from my PC (with DVI output) and other 30% will be watching cables TV.

I was wondering if anyone can comment on how is the quality of the picture when watching analogue sources (such as cable box). Does it do a good job streching the 4:3 picture to 16:9 ? How good the picture look when watching TV? Do you think the 8Ms is fast enough or better go with newer models that support 5/4Ms?

 In addition, any comments/info and recommendations regarding this TV will be appreciated.

Thanks in advance
