Here's a fountain pen that doesn't get the recognition it deserves: the Kaigelu 316A. It's inexpensive, well built, beautiful, and the nibs are among the best Chinese nibs I've ever used. I've had a couple of them for years, but recently added several more to my collection, and they're still excellent fountain pens.
