Looking For Roland JD-800 Waveform Cards

I am looking for waveform cards from Roland's SL library for the JD-800 synthesizer. The two cards I am specifically interested in are: SL-JD80-04 Strings Ensemble, and SL-JD80-06 Grand Piano. If you have these cards for sale or know where I might find them, please contact me. I currently have the Brass, Drums Standard, Guitar, and Accordian cards. I would consider trading these cards because I am mainly a piano player, so piano and strings are what I use all the time. I can be contacted at: naturallysweet@hotmail.com

Thanks,

Richard.
