Hm. An EF in that price range?
I can definitely recommend ANY Pilot fountain pen. I've had nothing but excellent experiences with them. I've never tried a Pilot Penmanship, but at about $9, I would definitely take the risk. Pilot nibs are excellent.
Your other popular options in that range are the Lamy Safari and Kaweco Sports. I think Pilot nibs are better than Lamy nibs, and Lamy Safari's grip sections have a triangular shape that some people can't get comfortable with. Additionally, the Lamy EF is broader than the Pilot EF. I have NOT had good experiences with Kaweco, so I can't recommend that brand and can say I am pretty positive I will never buy another Kaweco.
I hope this helps. If you're willing to go with a Japanese F nib and are okay with its appearance, I can absolutely recommend the Pilot Kakuno. I LOVE mine. I'd love to know what you end up getting and how you like it. :-)
