Or, don't bother giving this leech any money, and get plans for something like
this at many FTP sites.

Geez.  Really... a circuit such as this takes all of about 30 minutes to
think out, design, and _build_ a prototype of.

A SASE and a reasonable copying cost is OK with me.  But $5 is definitely
too high to pay someone for making a few Xeroxes and stuffing envolopes.
How much does this guy think his time is worth?
