So I got sucked into yet another part of B&B and I would like to start out trying some dip nibs and I currently found a lot of pens, here are some of the following names: They have names like HUNT, AMERICAN PENCIL, BRAUSE, ESTERBROOK, ALVIN, WILLIAM MITCHELL, FABER. they are very used most of the nibs look clean and without cracks. So my question to you is what should I look for in beginner nibs/pens and what should I stay away from? and what is considered inexpensive and expensive when it comes to nibs?
