Even though they aren't similar, I only used Kaplan and did fine. Kaplan drills the concepts into your head so that you completely understand the problem. Once you get to the more conceptual physics section on the real test, you will feel prepared and ready to go. If you have Kaplan, it will prepare you. If you still want something else, there's always the Destroyer and Achiever, both of which are discussed in detail elsewhere on this forum.
