I'm ordering one from Digikey today.  I've tried to
make my own active filters from the section in
Horowitz&Hill, but they never sound better than
passive filters.  Apparently you need a dozen or
so poles, precise R and C values, etc.  The ones
in the Digikey catalog look simple: 4 pins, Vc,
ground, in, out.  $10 or so, a variety of values,
even some adjustable ones I think.
