Hello.
I've been using FPs for about 50 years. I had a bit of a lull in the dawn of the fibre-tip and roller-ball era, but then I discovered that FPs were more comfortable. I got into collecting about 10 years ago, when I realized that as I developed arthritis in the thumbs, my old PFM was more comfortable, though I'd had it fitted with a stub nib, which was too broad for daily writing. I discovered the Zoss list (in the days when that list was fun) and asked about modern large diameter pens, and that's when collecting started.
I have now got some number over 100 (I'm in denial, so I won't count them), and I think my favourite pens are classic American ones of the '30s and '40s. Parker 51, of course, Vacumatic, Skyline, Duofold Junior, Sheaffer Balance. I don't have any really expensive pens, since my justification is that they all have to be practical writers. My very favourite nib for daily use is something like a fine semi-flex, as found on some Parkers (esp. a stripy Duofold I have).
I live in Auckland, New Zealand, where I've just retired from teaching medieval English lit. at the University. Our current cat is a young jellicle; she's still a little skittish, and spends a lot of her life up the tree in our small back garden.
Best wishes to all, including the old familiar avatars I recognise from other virtual locations,
Michael
