Hi everyone,
While waiting for the Kickstarter to start shipping official Paizo race starships, did find nice "Star Cruisers" online as decent proxies.
Here's a blog write-up if you'd like to see images:

Of course, the little guys are sort of like rubber erasers -- but the size is about right to use on a flip-mat. And, the package comes with 20 different types -- so it's going to be easy to create some *squadrons* of ships for more challenging fights.
