BTW, from what I've read in various sign forums, the Stika cutters are
considered kind of low end cutters.

No reason you can't use another cutter, anything that is rated to be
able to cut sandblast mask should handle Cutronics copper foil.

I made a couple of PCBs using cut vinyl as resist, using an old
Graphtec vinyl sign cutter. On the one that is undrilled, I used sort
of a surface mount construction using standard parts with leads
clipped short.

I think results could be very useable with the right brand/type of
vinyl and with CNC predrilled holes. It's very quick to do, on this
cutter I can do up to about 18 inches wide so that's a lot of boards.
Even on my old, slow cutter it's done pretty quickly and as you can
see there is very little undercutting. However, the adhesive on the
vinyl I used was a little stringy and caused some slightly rough edges.

There are brands of vinyl specifically made so the adhesive does not
reseal behind the cutter.
