That's the (infrequently updated) site for the protocol development project.
It's largely stalled right now while I'm working on new hardware that'll be
able to test the more interesting network features.

For the tracker hardware, you want:

There are also folks in Germany and Finland (and maybe Argentina soon) that
do some distribution within their countries, some of them sourcing parts
locally to help avoid import duties.  Depending on where you're at, it may
be cheaper (or at least faster) to go through them.  And of course, you're
always welcome to homebrew.  The firmware downloads are free whether you
bought anything from me or not.
