What is a good free(or $5) program you can use to make mockups of game maps, that has preset buildings, roads, etc you can plop down? 2D is fine, the ability to look thru in 3D later wouldn't hurt.

Also, I'll throw this in as a gimme since I made this topic: What's the best program, free or otherwise, for recording long amounts of in-game video?
