The Hanspree is at the top end of the 'budget unbranded' range of TV's at the moment and offer superb value for money. That said, the Samsung is a better TV and worth spending the extra money on in my opinion.
Black levels, shadow detail, picture processing, input compatability etc will all be better on the Samsung and other branded TV's.
That said, plenty of people have bought the Hanspree and are happy with it.
