The PDF will likely cost as much as a hard copy. I'd suggest looking for a used hard copy on
Amazon.com, or
e-Bay. Besides, with a hard copy, you save yourself the hassles of printing it off, or reading it off of a screen. I usually photocopy the pages I need, before starting work, to keep from getting my book too soiled -- I can mark it up, dirty it up, or whatever, without worrying about it. YMMV. Cheers!
