Java developers

I'm interested in taking the SCJP exam in a few months, but I want to get re-acquainted with the basics.

Do you folks have recommendations for training programs/exam simulations that are worth the money? A co-worker mentioned that Transcender makes some excellent simulations, but the package seems pricey.

Thanks for your input.

In case anyone is interested, the next London Java Meetup is on 27 February. Details here. It's an informal get-together of Java developers.

Apologies to those of you who are far away from London.
