Good CodeIgniter Books

[eluser]Freewolf[/eluser]
Greetings all,

I am getting into CI. Long time PHP programmer. Choosing to use this framework to build a few new sites. I am looking for some good references and/or specifically good reference books for CI. I see there are only 2 out for 1.7 and they do not seem to have very good reviews. So I am curious if there are any others out there, if the older ones might still apply and be good resources, and maybe any other resources (aside form this Wiki) out there on CI.

Thank you.

Blessed Be

Phillip
