Might as well throw in a vote for keeping the models resin, even though it now looks like I won't get the fleet boxes anytime anywhere near "soon" since I preordered through my LGS. If I'm gonna wait, I want to wait for what I ordered, which was resin.
Even with the bad mold slippage lines on my first couple packs, cleaning up resin is a snap. It takes for frick'n ever though with the sloppy molding issues. Other than that, it's light, paints up wonderfully and I like it better than hard plastic or metal.
