You might like OpenStreetMap! You can get the whole planet in a <30GB package: http://planet.openstreetmap.org/planet/

Granted that is the raw data, but you can extract the regions you need easily and then render them on demand.

I don't think it's such a good idea to link directly to such huge files from here. The directory would do just fine http://planet.openstreetmap.org/planet/ and avoid bots or inattentive clicks.

But good to know anyway!

Good suggestion, I changed the link.
