I agree with Starbuck -- ETS is your best bet. I even looked at old versions of ETS books, just for extra practice. Also, this may sound funny -- but I practiced with IQ tests, too. I know it's not related, but the speed and out-of-the-box thinking that those tests require helped sharpen me for the GRE. My strategy worked! I got the GRE scores I wanted. I also DRILLED vocabulary, and was ruthless about looking up every word I didn't know for months. The RC passages of PR and Kaplan are sometimes odd, or the questions/answers are flat out wrong, imo. I disagree with some of their strategies, too. Many of the take waaaaayyy too much time. All that to say, they're still worth looking over. Just because they didn't help me doesn't mean they won't help you! Good luck!
