FR4.  FR2 tends to crack and chip unless its really good quality.

The one thing I had to do was shim the upper blade holder just a tiny bit so
that boards with silkscreen would fit without scraping the paint off.

One thing I no longer see are replacement blades ( probably the wrong word )
for the beastie.  Used to be able to get them from Grizzly.  Fairly easy to
sharpen them although I've only done that once in many years.

Interesting.  Actually right now the Grizzly version is cheaper at $154.
