@NNNOOOOOO: the site I use gives me good speeds on my downloads no matter how long the video is. My maximum possible download speed is 230kbps and keepvid.com easily gives me around 120-140kbps if I download a single video, and an average of 70-80 kbps if I download multiple videos at the same time. So if you have a faster connection you could get more speed from this site. I don't know if the site has anything to do with the speed (the video is downloaded from youtube's cache?) but somehow this site is faster than the others I've seen.
@OpaQue: I haven't tried the site you've mentioned because usually it takes time for the video-mp3 conversion to take place online, right? If I want only the mp3 I simply download the video and convert it offline. I find that it is much faster this way.
