I am (still) dallying into the realm of infrared remotes and I was wanting
some suggestions on the cheapest way to make a suitable 40kHz oscillator
that can be easily modulated for output through an IR LED.

I basically would like to make production cost (if I ever decide to go that
far) as cheap as possible.  So...  I would appreciate some suggestions on
the cheapest way to go.  Can I beat a 555 in price without adding extra
support hardware?
