What kind of foam cuts well on a router-based CNC machine?

I have a CNC machine and I usually use it to cut plastic, wood, metal, etc. But recently I've been doing a lot of my own g-code programming and I'd like to do some testing with foam materials.

Simulators and backtracers can get you so far, but at some point you have to try it out in a machine and a mistake can break a bit or worse.
I figure using foam will lower my risk, still give me something that I can hold, measure, try to use in place, etc.
Not sure what kind of foam to use, though, or where to get it? I want something reasonably rigid, i.e. not like memory foam or something, that won't get too melty when cut with a router, and that will hold some detail.
