I've been using the Panasonic brand voltage supervisors from Digi-Key.
$1.09 in single qty ( $0.78 for 100 QTY).  They're easy to get and
come in all sorts of voltage ranges.
The root part number is
 MN1381 - X    where X is an alpha character corresponding to the voltage
setting.  Look them up on Digi-Key's web page.
