Hi Lawrence, there is a design for 2-transistor
switcher regulator here:
http://www.romanblack.com/smps.htm

This is a REALLY cheap regulator, and can use a
cheaper inductor than the ones usually specified
for "proper" switcher chips.
Total costing I did for 500 Q was about $0.35 USD
for the entire regulator, transistors, inductor,
caps, everything.
