In my original post I also added a bunch more from amazon that are under $50. It depends on what you want, cheapest way is with an internal card, most of them handle video, composite, and rf, so most everything you would want. I had tried usb devices in the past, never happy with them. Also, the nice thing about the internal ones with the three different inputs is most of them will also work with PAL, so you can use your PAL systems to play games or record videos.
