Your main choices for an internal PRI card are Digium and Sangoma,
though Rhino is now offering one, too.

Digium, Rhino and Sangoma all offer 1, 2, and 4 port versions.  Digium
and Sangoma offer them with or without hardware echo cancellation.
Sangoma also offers an 8 port version (with or without echo can).

I offer this information in an unbiased way in the hopes of preventing
a holy war.  I can't speak for the Rhino cards as they are rather new,
but both the Digium and Sangoma cards work well.  Many Sangoma users
feel that their cards are compatible with a wider variety of
motherboards, but that's the subject of much debate on this list.  I
administer a couple of systems with Digium TE410p's, and they work
well.

Digium offers unlimited support up until their cards are installed and
working.  They'll  RMA most any non-functioning card.  Sangoma offers
a 5 year warranty, and will generally help you out whenever you need
it.
