I too, went back and had to relearn cursive. Years as a mechanical drafter and block lettering with lead holders my writing followed suit. I chose to follow the Palmer Method while modifying it slightly to fit my own style. For less expensive but great pens check some of these out...
One of my favorites is my Esterbrook J... $40 vintage/used
The Pilot Plumix $7 new
The Scheaffer "school pen" $5-20 vintage/used depending on style or year
The Parker '21' $10-$50 vintage/used
Better view of the above pen...
These are my favorite low priced pens. I have an affinity for the vintage ones, and all are great writers. I would suggest one of the Esterbrook series, SJ (smallest) LJ (medium size) or J (largest) to start as nibs are readily available and just screw in and out, are easy to repair, great lever fill designs and abundant enough to keep prices down. Some colors in some sizes can fetch considerable money, but many more are to be had for the approximate prices I listed for second hand market.
