What would be comparable to the Foray 0.6mm ballpoint pen?

Answer 1

Try the Pilot G-2 series, Pilot G-2 05 can be found in many stores including Walmart and Target, are fairly inexpensive, and very reliable. Pilot also has another pen available that helps prevent check fraud. They come in many colors and never skip or dry out. Should work great for whatever you need your ballpoint pen to do.
