I've been circling the fountain pen reddit for a little while now and it's a similar thing. They spend thousands on pens, import ink from Italy, buy fancy paper, but their handwriting looks like a doctor's scrawl.
I almost went down that route! I settled for a $5 Platinum Preppy instead for a few years and picked up a Procyon recently. Don't think I'd spend anything more than that though. I tested out some $250-500 pens and didn't notice a difference but from Preppy -> Procyon is huge with how much smoother the Procyon is.
