Just wondering, I'm considering this certification in the next few months and study material seems to be very thin on the ground.

There are two books:

IT Project Management: On Track from Start to Finish, 2nd edition. (Approved by Comptia) &
Project+ Study Guide: Exam PK0-002

And as for practice exams, there's:

Transcender
Measure-Up

Does anyone else have any other recommendations? Other resources? That would be great
