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.
