I'd recommend a Noodler's Ahab ($23.66 on Amazon). What makes it fun is that the nib is flexible, allowing broader or thinner strokes depending on pressure. Plus, its a pen built to be hacked. After a while you can cut the feeding unit to your liking, making ink flow more or less.

I got into re-learning to write a bit over a year ago. I was a clumsy left hander with great keyboard skills but terrible handwriting. Take a look at IAMPETH, they have tons of material on vintage writing styles. I even followed Spencerian methods from the the nineteenth century.
