Video capture PC card

Is there any good , and cheap (and available somewhere) video capture PC card that can display the video signal from JAMMA (so, 15 Khz RGB) on PC dekstop screen or save it to avi (not monitor - i don’t need “JAMMA 2 VGA” one)???

Well, the one i have is called K World USB 2.0. I bought it for 40 bucks at Fries. It works pretty good if u ask me. Yeah, i dont know a lot about capture cards and whats the best and what not, but im happy with mine

what model ?
must have RGB - NTSC, SECAM, PAL they do not interest me
