I collect fountain pens (and other types of pens) and paper/stationary. I have been writing extensively by hand for many many years. While it is not my overall favorite, I think it's important for folks to know that from a writing quality and feel perspective that modern low-cost pens are actually /very/ good, and are the way to go. The Platinum Preppy is every bit as good as the majority of classic fountain pens, and better than many, very few are better, and you can buy it for under $20 basically anywhere.
The most important thing for writing with a fountain pen and having a good experience is actually the INK, not the pen, because the ink determines the flow, forgiveness, and the time to dry (which prevents smudging). Additionally, paper has a huge influence. I'd recommend investing in good quality paper with cotton in their mix. If you don't want to spend a lot but get good quality mass-produced stationary, G. Lalo and Clairefontaine are both good brands to buy.
