CISA / IT Audit Training in Los Angeles

I am working as a risk analyst and a liaison between internal/external audit and my employer. I am trying to find training in the IT audit field and/or in preparation for the CISA exam.

Can anyone give me advice on where to receive IT audit training and/or how to prepare for the CISA exam given that I do not have an enormous amount of experience in the field at this point? I am especially interested in any hands-on classes that might be offered, preferably in the Los Angeles area. Otherwise, online courses or do-it-yourself courses on CD-ROM would probably be beneficial.

Please don’t simply give me links to products – I’d like actual personal testimonials.

Thanks.
