We built a cheap ($150) recycler, which I noted somewhere on this forum.. we run it 2-3x/week,and are able to recover ~80% of our IPA using it.
Found it: scroll down to the bottom of this discussion.
only caveat - we originally built it with a 5gallon tank, but have since swapped out for a 3gallon pot, modified the distiller a bit ( to enable a closed circulation), and are cooling it with a powered chiller (as shown in the post). it takes ~90-100 minutes to recycle 3 L, and we do this 3x/week, generally.
