Digikey sells piezo 'elements' (such as #102-1126).

You wouldn't happen to know the variance in utility of these things? On all
electronics there are several piezo elements for under a dollar but they all
seem like they were for a specific application(piezoelectric speaker). I'm
wondering if there are limited applications for many of these configurations
or if I can pretty much interchange them. e.g., like rip up an old cheap
microphone that I don't use and get the crystal in there and then use it for
some ultrasonic stuff? I guess what I'm trying to ask is how general are
these devices? (Obviously dimension and quality would be important factors
but I have no idea how much)

I've found some piezo film sheets that are about 2-3$/sq. This is pretty
expensive I suppose but I imagine I can cut the things up into smaller
pieces(although I suppose this might dislodge the pieze crystal) and could
get many chips from it(since I suppose the average chip size I would use is
about 1 cm).

I'd rather just find some around the house though as theses things are used
in just about everything.

Thanks,
Jon
