I would stay away from brands like that, they are cheap for a reason. My parents bough a similar brand and after 6 months it crapped out on them. Stick with a reputable company, that won't try to sell you crap.
I HAVE BEEN LOOKING AT THE SAME SYSTEM AND AM GOING TO PURCHASE IT FIRST THING THIS MORNING. IT SEEMS TO BE ONE OF THE BETTER MOST COST EFFECTIVE DEALS OUT THERE. I WILL REPORT BACK AND LET YOU KNOW OF ITS QUALITY AND PERFORMANCE.
stay away from this excuse to waste 200 bucks the sub is basically a piece of crap distorts at the lowest volumes the remote doesn't respond half the time and for that matter the buttons on the front of the thing require 2-3 pushes to excecute a command and the picture quality is s**t even on my new 52" hdtv it has some serious issues with dot crawl my cable looks 5 times better i would give this unit a 1 out of 5
