I work at a electrical shop and iv'e got one of these Tv's. This model of Samsung (558/559) you can only get on the internet and the shop version of this Samsung is the 556. Its the same TV but with a different frame, the 558/559 had buttons on the right hand edge of the TV and the 556 has touch sensors on the actual frame on the right hand side. This TV is a lot better looking then the 556 i think, also if you just brush past the sensors on the 556 it'll turn the channel, sound or mode and it gets really annoying after abit. I also bought myself a Samsung 1500 blu-ray player and because this TV is 1080p the quality is superb.
If anyone was woundering the difference between 1080i and 720p is:
1080i will be better quality but any fast movement will be a bit blury and 720p will not be as good quality but better on the fast movements, so 1080p is the best because it'll be good on fast movements and is also really good quality on the screen. So a 32" TV with 1080p is superb and at this price its brill.
