I think it’s well worth it for the price. But I’m easy to please lol. It’s a metal pen with metal threads for where the grip section and barrel meet. The finial and trim pieces are pressed in, not threaded or glued. It feels solid but not bulky or heavy. And it uses the same nib as the 82 which is great in my opinion.
I’d say the one drawback I have is the grip is narrower side. So if you’re not comfortable with a grip that’s probably closer to a pencil then it may not be worth it for you.
It probably more depends on what you’re looking for in a nib. Gold nibs typically have some kind of bounce to them. The Viper is a hooded steel nib so it’ll probably be a much more stiff writing experience. But I’ve heard Diplomat nibs are pretty smooth writers. In my experience, Sailor nibs have some feedback and can “sing” on the page.
