[sdiy] Simple Cable recommendation

[Busby Bergson]

Hi all-

I've been searching for some mic cable, but I'm having a hard time
meeting the criteria I'm looking for. Essentially, I would like it to
be extremely flexible, thin, and cheap. A lot of the stuff I've been
seeing is PVC-insulated and I suspect I need something with silicone.
The only things I've found seem to be astronomically expensive. Any
suggestions?
