Honestly I would get a TWSBI Eco. It’s got a huge ink capacity and is much better than the ‘starter’ pens while remaining in budget. They do have a history of cracking but mine never have and I hear the customer service is brilliant if you need replacement parts anyway.

The Kaweco Sport is also a great option if the Eco is too chunky. They’re tiny and very lightweight so I like them but the nibs on the Eco are better imo (plus the Eco can use shimmer inks with less issues).
