I use a USB capture device that cost $10 or so on eBay. It's a knock off "ez cap" USB capture card.

It works well, but the drivers took some time to find as it only came with xp drivers and not windows 7, and it doesn't come with software to capture the stream, so if anyone snags this, they'll have to look for some freeware software (it works with twitch, tinychat, so if you're just looking to stream online, it works with that and ManyCam and SplitCam).

Quality is alright. It's not hd, and the inputs for it are svideo and whatever the red, yellow, white cables are (can't remember if it's component, composite, or whatever)
