Bite your tongue! :-)  Can't believe you'd actually encourage this behavi=
our=20
on the PIClist.
Actually, the lower-cost ones I've seen don't allow 3 events per day, sti=
ll=20
cost $30-$40 minimum, and I've already got a working PIC ckt already...=20
woo-hoo!  The $6 transformer is all I would have to spend money on, as=20
everything else is already floating around here.

Cheers,
