Please recommend a tuning book

I bought Richard Niemiec's "Oracle Performance Tuning Tips and Techniques". It's a good book except there're too many minor errors largely due to poor quality control of Oracle Press. Since I'm not nearly an expert, there might be a lot of serious errors I don't recognize. What do you guys think of these following books:

Mark Gurry's Oracle Performance Tuning, 2nd ed Ahmed Alomari's Oracle8 and Unix Performance Tuning Eyal Aronoff's Oracle8 Advanced Tuning & Administration Lynnwood Brown's Oracle Database Administration for UNIX Systems

(Note: I already have the consistently highly-acclaimed Steve Adams's
Internals book and Velpuri's Backup&Recover book. I wish Steve Adams could write a performance tuning book)
