Looking over options for CCNP prep... and advice?

I'm interested in taking the CCNP routing and switching (642-902) sometime this year, after passing ICND1/ICND2. For the previous two tests, I bought a bundle from the Cisco Learning Network Store, which was the test fee + a prep exam I could take as many times as I wanted (very helpful to test where I am at in my studies, what I needed to focus more on, etc).

My question is are there any similar packages I could look over? What did you guys use to prepare for this test (and the other two)?
