Safe wanted, burglar protection does not matter?

I'm looking for a safe for home, which is only the most important documents, memorabilia, possibly a 15 "laptop secure. (Hotel safe size is enough)

Paper and electronic data carriers must therefore be protected.

The burglary protection is insignificant, important to me is the protection against fire and water.

The wikipedia entry:

I find a little ambiguous.

Also, I would praferieren a combination lock, what can you recommend?

If it is a small wall and furniture safe for less than 50 euro, then forget it, the things are not robust and easy to crack, rather they are suitable as a dummy so that the culprit is satisfied. In addition, without heavy weight or concreting is carried away quickly and then cracked.
