Oracle University courses - opinion?

Hi,

I am looking at instructor-led Oracle DBA courses (in London), specifically as preparation for taking the OCA/OCP Oracle certification exams. The Oracle University courses appear to be significantly more expensive than some of the other instructor-led courses I've seen and I'm wondering if anybody who has attended DBA courses can help here - are the Oracle University courses worth the extra money? And/or do you have any training company recommendations in the London area for Oracle DBA courses?

Many thanks,
Renee Dekenah
