Corbett,
The link that laffindude just posted is for a complete set of Poker key caps in ABS. There's a member here called IMSTO who is a broker for Taobao and you can contact him directly should you want them. According to Google, 50 Yuan is roughly $8. That's pretty cheap if that's correct.
You can contact IMSTO directly
via PM, or post a thread in his
vendor sub-form here on GeekHack as well.
Hope that helps!
