My interest is having a dip pen to quickly and easily try out different inks (and papers) without cleaning and inking up a fountain pen. One fellow writes that he can write about 1/2 of a page without re-inking, which is much more than I might have thought.
Interestingly, both Pilot and Sailor (and probably others) offer dip pens. You generally get a steel nib. I have also read about handles that will accept a Jowo nib (and feed perhaps). The Sailor dip pen can be fitted with an optional feed (for $3). These are inexpensive and look like fun.
Huge numbers of these pens (what we call today a nib was called then the pen) were manufactured. There are plenty on Ebay. I have a nib holder I bought back when I thought I might try to learn calligraphy. I plan to see if an 048 Falcon will fit into it and go from there.
