Chris:
I didn't use the filter (in case you didn't notice), and instead, used my yama metal filter. I can "donate" it to the cause, and send it your way with some paper filters (or to the next contestant), so others can use it; alternatively, they can use their own filters; my glass corning rod from B|Java did fit (I have the shorter one).
The only caveat: the metal ball thingies are kind of big, and grate against the surface (and get jammed between the bottom of the glass siphon and hotplate), so you have to be gentle pushing down.
