I picked up calligraphy recently and found it a very relaxing art form. Besides that I never used them, but there is a whole world to learn about different styles and purposes behind them. What do you use them for?

I think it really depends what you want to use your pen for. If you want it just for signatures, I would get a pen that has a broad nib. If you are using it to write a lot, you will have to experiment. Depending on your paper, you will have to change the nib sizes.
