for reason like software, performance, quality, and ease 
i have an elgato game capture hd and i would definately recommend buying that instead of any other recording device. You get all of the necesary cables in the box, a really easy-to-follow setup guide (i will literally take like 2 minutes) , the elgato is considerable light and small so you can store it practically anywherewhy is everything so expencive i just want to recorde for free damn you Sony (Ps3)
and the video quality is veryyy good! 
the most amazing site on earth... AMAZONyeah but where do i buy ?
haha, thats where i got mine from
