You might try Jameco.  They have a set of Voice Record / Playback chips,
from 10 seconds to 240 seconds.  The 10 second chip (Part No 141671) is
only $4.95 >> 4.49 for 10 or more (p. 15 of the Nov-Jan. catalog with 
Telsa on the cover.)

I have not tried these chips, but in a wild moment imagined creating a
midi Mellotron.  All you would need for a full octave is one PIC to
capture midi in and produce 12 on/off triggers for the appropriate 
notes, then 12 10-second chips with the sample of your choice. When a 
chip has rolled to the end of the 10 seconds and makes an ugly clicking 
sound like the tape has just snapped -- hey, that's pure Mellotron,
baby! 
If one were really clever, you could probably setup a system from a 
soundblaster to the chips to sync the download of new samples (or even 
upload them to .wav files for storage).

You could certainly buy 4 chips and create an interesting little
4-pad sampler like the Roland (?)MS-1.
