A good Spanish dictionary?

I went to the bookstore last night and saw the Oxford SPanish dictionary and the Haper Collin dictionary. They're quite impressive and heavy. Yet I am going to start Spanish in a few days and completely new to the language. So what should be a good Spanish dictionary for me, as I consider accelerated courses to be proficient in the language in a few years?

Is there any good dictionary that come with a CDs, with pronunciation like the English dictionaries's ones?A good Spanish dictionary?
Although the DRAE is the "Oxford English Dictionary" of the Spanish-speaking world, I assume you want a bilingual dictionary. I'm a fan of the Collins dictionary, the one that cost about 拢25/$50 in 1997. I've been using them for years, both for pleasure and in business.A good Spanish dictionary?
