I'm looking to buy a second tv for my bedroom. I'm not sure if I'm going to get a 32" or a 40", but leaning towards the 40". So I've been reading reviews on this new brand called TCL. It seems like a Roku tv and I know nothing about them. It's the cheapest, but I've read negative reviews on Roku setup and the ads. So then I looked at the Samsung and by far it seems the best, but pushes $400, nearly double the price of the TCL. Which would give me most bang for the buck? The other reason for buying is in case my 6 yr old Samsung goes bad, I'll have a spare.
