Re: 100 meg resistors $2.00 ea



Keithley Instruments has a very nice application note (booklet) on current,
voltage, and resistance measurements:

I developed a unit on drawing circuits and resistors using a graphite pencil
or mechanical pencil:
see:
"Graphite Pencil Line for Exploring Resistance," L. D. Woolf and H. H.
Streckert, The Physics Teacher 34, 440 (1996).

You can easily draw resistors with resistance from kohms to Mohms.
