'Low frequency ceramic resonators'

       Assuming that ceramic resonators are, in fact, cheaper than
crystals, are they available in very low frequencies?  All I have been
able to locate is 4 MHz and up parts.  I would need one that
worked at 32 kHz.  (Running at 4MHz and sleeping 99.9% of the time
is not an option.)

       If anyone knows of any, please reply to me at spam_OUTcostallsTakeThisOuTspamcuug.ab.ca
or post to the list.  SMD parts are preferred, BTW.

       Thanks for any info.

Sorry, Sean... Ceramic resonators aren't available at those
frequencies.  Even if they were, they'd be about one inch square and
would be VERY shock-sensitive.  You'll have to use a crystal for
this application.
