I wouldn't go with a product that cheap if it has no reviews. I personally use the Elgato and recently upgraded to the HD60 model. I like the Elgato since it functions just as I expected it to, it allows for good quality game capture and streaming, and is very customizable for a capture card. I've had very few issues with either model and its ease of use makes recording very simple. It has a few nifty features like flashback recording letting me record games I may not have actually intended to record which adds to the experience.
Of course the price is a major thing for many if its outside of your range you could try Roxio but I've never used one but I hear its okay but the quality is lower however that's to be expected from a cheaper product.
