8/8 rules on a reliable basis should be easy with the crudest of
etching setups provided you can see the process and not just depend on
a timer. Etching has always been the no-brainer step for me.

It's the printer and/or transparent media that's the limitation at
finer rules (below 6/6) IMO. A combination of irregular spacing and
rough edges in the case of inkjet or toner fuzz in the case of laser
seems to be the show stopper. Magnification of the artwork is all
that's required to confirm this.
