Hi,
maybe Digikey has what you're looking for.

Roll your own!

Air core inductor:
33.035 µH

Coil diameter  15mm
Coil length   10mm
Number of turns 50 t

Wire length 235.62 cm

If you want to use a soda bottle cap as a form, then try this...

Coil diameter  30mm
Coil length   14mm
Number of turns 32 t

Wire length 301.59 cm

@Kryoclasm:
This guy is actually designing a SMPS. I don't think an air core inductor will work too well for him. I suspect he targets a efficiency > 1%.
EDIT
Also for filtering purpose an air core inductor would not be suitable. An iron-powder core inductor would be much better.

Sometimes it is really faster to make your own, than wait for it week or two to be delivered. It is not so hard, google it, a lot of instructions out there.
