I voted "Not worth buying"... I play a spellcaster, but one with a limited and proscribed spell list (AEG's Tinker class). Plus I already have all of the books used as sources (but not the Dragon magazines), so I have 90% of the content already. Slightly more ease of use and some errata on content I already own isn't worth anything close to the price of the book for me.
