From my experience, I rather liked the Elgato Gaming - Game Capture HD. A friend of mine has one and the quality is nice, and I know for the longest time ReviewTechUSA was using Elgato iirc. I could be wrong but a youtube channel I watched frequently a year ago used it and I liked the quality from his posting. Of course we all have our opinions on things but I can at least link you something for
information. The amazon page has a lot of information and reviews for you to check.
