Vic,
Front panel marking was at least one of the things I wanted to be able
to do when I recently bought a large-format laser engraver. There is a
metal-marking compound called CerMark that can be used to put a dark,
permanent mark on the metal at whatever resolution the machine supports.
(in my case 1000 DPI)
I also have a CNC router/mill to engrave lettering with which
I then fill with enamel. That method takes more time, but is somewhat
more durable. It also allows the use of color(s), which the laser
process does not.
I mention these because you'll get very high quality results, and you
could probably find a local business that does one or both of the above.
Most larger engraving shops have the equipment, at least.
