Um, looking for a pen that can be a dedicated red ink drinker. Mostly this is for marginalia and other corrections to academic papers, so it needs to be quite fine and not too scratchy.

Does anyone have a recommendation for this kind of set up?

At the moment I have been looking at:

Moonman M2 (~0.38mm) - costs about $15

Pilot Custom Heritage 92 (fine or extra fine) - costs about $100

Pilot Custom Heritage 912 PO - costs about $140


I would prefer not to spend too much (the list above has a large price range, and is only for example). If the M2 is likely to be up to the task, based on other people's experiences with it, then I will likely go for that but I'm open to other suggestions.

TIA
