Well...fourth time's a charm. I picked up yet another 2000 from a fellow FPNer, and it arrived today. I have to say, I'm quite impressed: the nib is silky smooth and a consistently wet writer. I've tried it on a variety of papers, and I'm very, very pleased with the performance. Not only is the pen a smooth writer; it has a nicely expressive nib by modern standards, which produces beautiful shading with Diamine Prussian Blue.
Anyway, I just wanted to finally give my recommendation of this pen. Maybe the quality control isn't tops or maybe I just had terrible luck with these, but it's a sweet pen once you get a good one.
Just another testament to never giving up
