That's a tough one.
Well, I have a friend who took a class from Bruce and he thought it was very good.
If you think you are ready, or almost ready, for the
SCJP then the Java class may not be as helpful. Try a few of the mock exams that you can find
here and if you do well then maybe you don't need the Sun class.
I think the bottom line is that you take the class that sounds most interesting.
Just an opinion...
