EE264 textbook and solution also GOOD for EE QUAL

I'm selling
Discrete Time Signal Processing Second Edition and its solution book. (Oppenheim)

1. Textbook - asking for $15
   The textbook is international edition. Softcover
   The textbook for ee264 course is "Discrete-time Signal Processing Third Edition". This third edition is sold at $130 at amazon. I'm selling international edition of second edition.
   I'm not sure what the major differences are. But be careful.
   The book is also very useful for preparing EE quals. In this case, I don't think you need third edition. :)
   Inside is very clean. I had two books and I didn't use this book.

2. Instructor's Manual for Discrete-time Signal Processing Second Edition. -asking $15 for each
   I have two same books. One is new and another is slightly used when I prepared ee quals..
   But I cannot see which one is which. Both are in great condition.

You can buy both textbook and manual at the same time ($30) or you can buy seperately ($15 for each books).
