Hello Paul,
I'm looking to get back into b&w printing (A3 size) after a few year's absence.
I'd started b&w printing a very long time ago with an Epson 1160 and Piezography and left when the green tint problem became apparent. (I know it's been fixed a long time ago also.)
After that I used an Epson 1400 in a 3-MK setup which was a joy to use, but that was last used some five years ago. There are some old printers on the used market but I do not want to go that route.
Today, an Epson XP-15000 or a Canon Pixma Pro-100 would be my choice. In a 3-MK setup if possible.
All the best,
