It's a worthwhile pen to have. Extremely satisfying and worth the price unlike a lot of snooty high end pens that are worse than ones you can get under 200.
The lava stone absorbs your sweat as you write and stays cool. The filing mechanism can clean out leftover ink in an empty reservoir completely with enough pumps in water. And the cap's locking mechanism/vacuum seal is the best I've ever seen. The nib is excellent too, but I had to fix mine a little and re-tune it (which I don't recommend doing yourself).
I have been looking into nibmeisters today. There are many in the US and one in Canada so I'll definitely look into some custom grinds at some point.
