Well, the most I spend on a pen is on the low end Waterman Apostrophe. It writes really nice. But I couldn't resist getting another Pelikan Pelikano pen and that one, although it doesn't look very posh, is and absolute dream to write with.
I was thinking about getting a nice Pelikan pen, but I'm so happy with the Pelikano that I don't remember why I wanted it.
Redleader if you want to know what fountain pens are about, get yourself a Pelikano pen.

Fountain pens don't need to be expensive to be good. with a ballpen you need to controll the pen because the ball is rolling all over the paper. A fountain pen just glides over the paper when
you move it, and that causes your handwriting to look better. Also the ink looks much nicer than ballpoint ink.
I did go a bit crazy with inks though. I've got Waterman Blue Black(which is green, light green), Parker Quink Black, Aurora Blue(is violet in my eyes), Private Reserve Tanzanite (purple) and Visconti Blue.
Milkpowder, you wanted to know about Visconti blue? It's a gorgeous blue. If it was a headphone I'd call it upfront.
In a few weeks I'm getting 3 more ink colours for my birthday. And I've got a sneaking suspicion those will be Diamine Umber(green), Diamine Sepia and Waterman Florida Blue.
