I passed the SPHR exam in June of 2012. I am now selling the following materials, which I used to prep for the exam:
--"SPHR Exam Flashcard Study System" Published by Mometrix Media LLC. I don't see an edition or year printed on the cover, but I purchased it new in early 2012, so I assume it is the most recent edition. This includes a link to online bonus materials. No marks or notes written on the cards.
--"PHR/SPHR Practice Test" by Aaron Frias (2012 edition). This is a 225-question practice test with answer key and explanations. I did not write in this book or make any marks.
--"Kaplan Human Resource Certification" book by Karen Yasgoor and Susan Bressler. 2008 edition. Very useful book; Includes 2 practice PHR and 2 practice SPHR exams, with answers and explanations. No marks or writing in this book.
I'll sell all three for $50 shipped via media mail to the continental US. Contact me if you're interested. Payment would need to be via Paypal.
