I have a pen obsession. It started simple with Office Depot etc and quickly expanded. I am now a dedicated user of fountain pens and they are AMAZING. My preferred fountain pen is the Lamy 2000 in fine nib or medium for a heavier stroke.
I am currently going to back college. I take notes for hours and hours on end. The Lamy 2000 is by far the best, most comfortable pen I've ever used.
I use noodlers bullet proof black ink in my pen of late, but also enjoy Lamy inks too.
If you don't want to spend the money for a 2000 Lamy safari pens are decent, but no where near as good as a 2000.
