I use Steadtler, they seem the best but with a too acidic etchant they 
fail all the same.
Buy the red one, they are the best.

You can buy them in many sizes, with very fine tip.

sharpie _is_ the standard somehow. in europe it is edding 3000.
I think they changed the ink formulations the last years (no "bad" 
solvents,
toulene, xylene etc.., environmentally friendly....).
Most pens i tried do not work.

I use Toner Transfer and pray to not need any corrections with a pen.
then i closely monitor the HCl molarity of my etchant which enables me to 
use
the staedtler.
