http://michaelis.uol.com.br/moderno/ingles/index.phpThe Michaelis is the most known brand over here, it's really reliable and it's available in physical form. However, I don't know where exactly you can find a vendor that exports.
I've never seen a dictionary with European and Brazilian words. Personally, I would rather have one for each variation, as it would cover all rare discrepancies of each portuguese variation.
