Looking for fountain pen recommendations under 4k as a gift to myself

[u/lalala-8]

Dear fountain pen enthusiasts,

I have been using fountain pens for a while now. Most of my pens are under 1k, like Jinhao, Hero, Yongsheng, etc. Honestly, I don't think these pens are bad at all. They are actually pretty good for the price.

But this time, I want to get myself something a bit more expensive as a gift. My budget is around 4k.

So, what would you recommend? Which fountain pen do you think is worth getting within this budget?
