Fodor's See-It travel guides or DK Eyewitness travel guides, and why?

I'm going to Germany for 51 days and am staying with a native, but we will be traveling around Germany in parts that she hasn't been to yet and I want to be prepared to know what to look for in sightseeing. Keep in mind that I'm 17 and don't have tons of money to throw around and am interested in the modern side of Germany and not just the ancient Altstadt side.

I would recommend a Lonely Planet guide (especially since you're on a pretty tight budget). They're kind of focused to a younger demographic so you will have a lot of great resources. I just got the London one and even though I've already been there, it's given me an amazing amount of information. I do like the DK Eyewitness guides because of all the pictures and history but Lonely Planet is the way to go.

I never travel with out a Fodor's guide. The walking tours are the best you can get and they give all kinds of little tips and secrets, along with ideas on what to do if you have only a certain amount of days in an area.
