von Oppenheim family tree?

Does anyone know where I can find a complete and up-to-date family tree
for this German banking family?

The great genealogics website has some info but appears to be
incomplete.

Schwennicke, Vol. XXI (?, I do not know whether this is the right family)

I can not vouch for the gentleman below nor am I aware of how he
prices his research but apparently he includes the various Oppenheim
branches:

Thank you for this information but I am looking for something more in
line with my current budget-- which basically means FREE information.
Anyone with FREE information-- that would really be great!

Thanks anyway!

I am particularly looking for male line descendants.

Thanks again.

Up-to-date, but perhaps not complete, and well you know ...:

I note that the wife of hereditary prince Heinrich Donatus von Hessen is
a descendant of Salomon Oppenheim.
