I think by improving your Google-fu, you'll stumble upon a lot of good stuff.
I've found documents from Schweitzer Engineering Labs, GE, my alma mater (Texas A&M), and other stuff to be helpful. Sure, it's not as 'good' as having a real book in your hands, but they add to the knowledge pool.
At a minimum, buy the NCEES Sample Exam. From there, look at the problems, and work the Google magic on solution methods. For Power, per unit, induction motors, power transmission, protection, NEC, NSEC, etc. A lot of it is "out there", especially in .PDF format, you'll just have to collect it. If you're doing one of the other electrical disciplines, I'm sure there's stuff out there for them as well... but you'll still want the NCEES Sample Exam.
