Exactly.. I'm sure I'm not the only one on this list that has contemplated home
use of liquid helium or even making the stuff. Hey, if Onnes could do it 100
years ago, so can we.
I assume the cryogen isn't being used for superconductivity in this case, but
for just being cold. In which case, perhaps LH2 or LN2 would serve almost as
well. The latter, particularly, is pretty manageable (i.e. You don't have to
make it yourself).
Cost wise, I like the snippet I read in Scientific American a decade or so
ago.. LN2 is the cost of milk, LHe is the cost of fine scotch whisky
Is a obsessive precision worth a bottle of scotch?

This has got to be one of the best lines in a time-nuts email :)
