I've been using and collecting fountain pens for about five years now. If I had to do it all over again, I think I would use Richard Binder as my information source. He is a very respected fountain pen collector and repairs pens too and has a blog and sales inventory of vintage and modern pens. At the first day of every month he puts out a tray of nice pens for sale and they are gone in hours of showing. But the best thing about getting a pen from Richard is that he services and adjusts and tunes each pen to bring out its inherent characteristics, whether new or vintage. My current fav is not a Binderized pen but I did learn so much from him to get to the point where I knew what I really wanted and really liked.
