What Enterprise IOS Do You Recommend for 2500 series?

I have the following IOS to choose from:
12.1.27 IP Firewall Plus IPSec 56 Enterprise
12.1.27 IP for 8 8 Routers (?)
12.3.6 IP

I have one 2514 and one 2520

Thanks

For a lab I usually go for the latest, greatest, biggest, baddest IOS that will fit in Flash. After a while you don't need to practice IOS upgrades anymore and it just takes away from study time for the new fun stuff having to swap out the IOS.

For the CCNA, you might get more benefit going for the newest IOS version -- you don't need the Crypto (unless you want to access your lab from the internet).

How do you get the IOS image to update it? I've heard that once you pass the exam you can log into the Cisco website and get all the goodies. But until then, how can I get the latest IOS image to upgrade? Thanks.
