I just bought these from amazon recently and love them!

Appears to take a Pilot G2 refill, at a quick glance. If you like the pen but don't like the ink, switch the ink =)

If this is the one you're talking about, it takes Pilot g2 refills. I recommend the Schmidt Ceramic Rollerball 888. They have good ink and almost never skip unless you let them dry out for a bit, but all it takes is a bit of scribbling to get it back out.
