Yeah the 3d stuff is a little expensive on certain things, but really not much more than if you got something done in resin, better quality in some regards.
I got a few things in today from Shapeways. First 24 1/2256 x-wing in cruising position. 24 1/2256 Y-wings, and a 1/2256 corellian gunship. The x-wings and Y-wings are tiny, I dropped a couple on the carpet, I'll never see them again. The gunship is really cool, really nice detail. Its hollow and it has a hole on the bottom and in the engines, so mounting lights would be easy peasy. These are all from J_Roncho he does a bunch of 1/2256 stuff. The grand total was about $25 w/free shipping, a little high, but its worth it. They'll go great with my 1/2256 fleet.
