Recommendations for SD card stoarage

I have an arduino duemilanove and would like to add SD storage to play sounds and such. What do you guys recommend? I'm kind of cheap too lol.

Thank you! That looks like what I need. With all these "shields" you can attach to the arduino, I was wondering what you do if you need the funtion of two such as this one and the ethernet shield.

The adafruit shield comes as a kit. You put it together. Just replace the male pins on the bottom of the board with the long pin female version. Then, you'll be able to stack another shield on top of it, as long as the pin usage does not involve conflicts.
