Pacer charges per page, but if you keep it under $30 in a quarter the bill is forgiven (so free).
You'll eat up 300 pages pretty quickly - there's roughly 20 filings between now and March 10 which I'm guessing is around when this article came out, probably too many pages to fit under the free limit but then again a lot of the activity isn't very interesting.

Beyond that as another poster noted, you'd have to buy the additional files via PACER.
