Regarding the circuit he
http://www.kwarc.org/bulletin/99-04/tech_corner.htm

Does this voltage doubler work any "better" (better regulation, better
transformer utilization, etc) than the classic 2-diode, 2-capacitor
doubler (as seen in e.g. the HP-23 supplies)? I know it uses more
parts; what I'm wondering is whether the extra parts actually provide
any benefits, and if so, under what circumstances.

Does anybody have any actual experience with this circuit?
