You can get a Pilot Varsity or a Platinum Preppy for just a couple bucks, and they write pretty dang good. It's a great entry point in to fountain pens.

Having nice pens makes me want to use them more, and writing more has helped me organize my thoughts better, especially when writing code. I'd highly recommend it to everyone.

Anyone looking into this should consider the TWSBI ECO and Pilot MR as well. They're more expensive than the varsity or preppy but still very affordable.

The TWSBI Eco is an excellent introduction pen. Nice and smooth, the triangle grip means you hold it correct without thinking.

Only downside is no cartridges (not that I find this a downside)

I will second this as someone who really likes these two pens and was disappointed in the Preppy.
