My girlfriend got this little dictionary for me after a complained about constantly going online for translations (www.mijnwoordenboek.nl). This book has been a very big help. It's very small, but has a durable cover. The immediate translations for some words are outdated, so mijn verloofde tells me, but she can always understand the point I'm trying to make. Also, there's a section in the back that gives some additional instruction, like the correct way to conjugate "to be" and how to tell time like they do in Nederland.
Whether you get this dictionary, or the Langenscheidt, I think you'll be pleased.
