I managed to pick this TV up REALLY cheap from the shop that I work in as it was ex-display (albeit only for 4 weeks - i know, cos I put it there!).
I upgraded from a 32" LG and I am very pleased with the noticable increase of sharpness, clarity and contrast. I was concerned about it only being 50hz, but decided to take a chance on it. It paid off!
The whites are brilliant, as are the blacks. Sky HD was installed a week after getting this telly and the results are amazing. Every blade of grass can be seen on the golf and even the sewing marks on the presenters clothes are there.
The xbox looks fantastic too.
If 50hz doesn't put you up or down, and you are looking for something bigger than 32", this is a great 40" TV.
