So Hard to Find A Canon EOS D60 USB Cable

[seemnotbad]

I'm in a China trip now and my sister asked me, who knows nothing about camera, to buy a cheap USB cable for her Canon EOS D60. But I find such cables in China are also not cheap. The two are have been the cheapest i found online: http://www.tinydeal.com/usb-cable-for-canon-p-778.html and Canon EOS-D60 USB Cable. The prices are different but i can't see any difference in themselves. Besides, some other sites sell much cheaper EOS D30 USB cables whose ports are the same as ordinary MP3 players'. So anyone is to tell me which to buy? I don't like this sister very much, so I are not gonna look like a fool before her.
