Personally, I got the cheapest I could find, turned out to be a Samsung as well, and it's been serving me well. My logic is that getting the cheapest you can find, with something like this where the specification is relatively rigid, means that even if it fails and you need to replace it, you might still only end up paying as much as you would getting a more expensive one to start, and a new standard will come at some point anyway - not that the one I have now seems like it'll fail. Seems good quality, especially for the price. But frankly have no idea about model or anything; Just that it was the cheapest on Amazon and it says Samsung on it
