I've seen them as low as $7, but some look 'cheap'.

The ones from UroTuner don't look too bad:

Yeah, just search 'O2 Defouler' or 'O2 Spacer' and check results.

I prefer the ones without any media or 'baffles', but suspect they would work too.

EDIT: Danny C. from the efi forums recommended the Innovative ones, and grabbed a couple of those. I have some others too, but just wanted some on hand.
