I don't know where you are based, but if in the USA be aware that Sailor pens have a dramatic markup over the home and other foreign markets. I generally advocate buying local but both my Sailors have come from abroad and saved me a lot of money. Actually I probably wouldn't have brought them at all if paying US prices. My Pro Gear Imperial Black came form Amazon Japan for $200. The same pen is $470 plus tax in the US! My Cult Pens exclusive Gunmetal PGS Midnight Sky was $180. Regular PGS run around $220 and that is without the plating on the Cult Pens edition
Buying from abroad has its risks and drawbacks but when using a reputable seller it can save you $$$. The Gentleman Stationer discusses the situation here in his re-review of the Imperial Black. https://www.gentlemanstationer.com/blog/2019/2/2/battle-scars-revisiting-the-sailor-pro-gear-imperial-black-after-five-years
Also be aware that the 21k nib, while having very little flex, is actually quite soft and easily sprung or bent if roughly handled.
Did you keep your Visconti Bronze Age? That is one of the few pens left on my wish list but I know their nib QC is abysmal and if/when I have the funds I know I will have a hard time paying their prices for a pen that I'd probably have to send straight off to a nibmeister.
