Yeah, that $900 is for a 25-pack -- the lowest volume they apparently
deal with for on-line orders -- so that's $36 US each. Not too bad.
Also note, though, that the stronger model only contracts with a force
of 70g (~2.5oz) -- not very strong in the Lego world -- and the weaker
model less than half that even. Both have a throw of 4mm (~5/32in) and
require a spring to re-extend them after contracting.
Certainly an interesting technology, but probably of little practical
use to Lego enthusiasts, at least in that form.
