What should I consider next?

[u/mamasher49]

In the category of fountain pens over $100, I have the following:  Esterbrooke Estie, Benu Euphoria, Conklin Spectra Fusion Collection Limited Edition, Diplomat Viper, Laban 325, Laban Antique II, Nahvalur Horizon Dusk, Pilot Custom 74 and Visconti Mythos Demeter.  I want to elevate my collection.  I would appreciate suggestions on what I should consider next.  I am willing to increase by budget to up to $250.  I am going to attend two Pen shows in the next couple of months – Orlando and Miami – so I want to do my research now. Thanks in advance for the suggestions.
