Hello,
Just wanted to throw out a few more options for sound players. These
options all require an additional amplifier and speakers.
1) Medeawiz DV-68 CF Card Player ($200 for 99+ buttons)
Think of it as an industrial strenth IPOD. This player actually puts out
MPEG4 video as well as MP3 sound. Plays from a CF card that you can
download sounds onto from a computer. With a few accessories, you can hook
up multiple buttons (99+) and play multiple sounds (99+). Plug and play.
(*Can also communicate with a microcontroller, but the serial protocol needs
help).

2)ISD Chipcorder ($30 per button)
A cheap electronic chip that records sound off a line-in jack and stores it
into memory. I believe something similar is used in those annoying greeting
cards. You can buy a prepackaged kit from Cowalacious Design, but you need
one kit for every button. Great for single sound applications. It comes set
up to be triggered by a pushbutton. Fairly Plug and Play.

3) Arduino with Wave Sound Backpack (~$100 for up to 20+ buttons)
I love the Arduino Microcontroller, but haven't tried the sound card
addition yet. It basically converts the Arduino microcontroller into the CF
Card Player (similar to #1). The advantage is that you now have a nifty
microcontroller to control when and what sounds are played, etc... But for
simple pushbutton applications, you'd be better off going with a dedicated
CF player, and not fiddling with DIY kits.

*Just an idea, but how about a painted mural with invisible touch panels
embedded in the wall. Touch a creature and it makes a sound. Let me know
if you are interested, and I can send additional info on reliable touch
sensors.
