A couple of weeks ago I launched GNS3Vault, you can download any Cisco Lab you like here for free and use it with the GNS3 software.
This is ideal when you are studying for your CCNA, CCNP, CCSP, CCIP or any other Cisco certificate. Even if you just want to upgrade your network knowledge this is a good place to check out.
If you haven't seen the website yet, here's the link:
Have fun, and good luck studying!
