looking for small, cheap knobs

[Hess Hodge]

Hello,
I'm trying to find a good source for small knobs.  I need around 70 of
them.

Specifications:
-- 1/4" shaft, round
-- .5" diameter at base maximum
-- cheap!!!  ;)

I have looked throught the Mouser and Digikey catalogs, but the knobs were
either too expensive, or "ugly"... ;)

Any suggestions?

Thanks,
Hess
