Good SAT practice books for Math?

i personally really like the princeton review books. i used them for the SAT, ACT, and the MCAT and thought they were all quite good. there are lots of practice problems, which i thought was helpful. i used the Kaplan review book for the PCAT and it was OK. the way the material was presented was good for teaching it to yourself and the practice problems were fine, but the practice tests were not very representative of the actual test (one example that i found was the review book barely touched on organic chemistry and there was a considerable amount on the actual test).
