Capture card?

[Cream Soda]

I'm not too familiar with them but would like to record Wii U footage (Mainly smash) for a youtube channel.

I may consider wanting to stream, if the price difference isn't too great, but if it is, simply recording from replays will suffice (My area doesn't have Fios anyways, so I doubt I'd be able to play and stream w/o lagging).

What products should I be looking into, what to avoid? Assuming I know absolutely nothing about capture cards (because I don't)

Most anything from Avermedia, Happauge, or Black Magic is solid. I use the black magic stuff personally, Avermedia is the most budget friendly though.
