Interesting... I went to the one in Rochester, but the version they showed
only did lowpass... they said the version that highpass and bandpass
wouldn't be out until sometime in the summer.  If you actually saw the
highpass or bandpass working, that's a very good sign.  I downloaded the
one on their website today and it still only did lowpass.   I am the
original poster and I want to thank all who replied.  Here is one more
resource that I found quite helpful that wasn't mentioned previously:

It's a java applet that allows you to do filter design.  Not quite as nice
as filterlab, but it does highpass and bandpass.  I placed an order today
for the necessary 1% resistors, so hopefully my problem is on the way to
being solved.  Thanks again for the assistance.
