Dude, Incursion truly rocks. My sole complaint about the game was the "bling" factor...the cardboard standies from the first printing were great as far as gameplay goes, it made detecting facings more obvious, but the toy factor was missing. That's what made Space Hulk a better game than it. But now....yeah, it's going to be the best corridor shooter ever.
Regarding the plastics - if you brush on thin varnish and then spray with acrylic dullcote (or Krylon) before you paint them up, the models become almost as good as working with metal. Very stiff, adhesion is great, and they come out pretty good. The one advantage I think that these plastics have is that you can "make them your own" by changing the poses on the extremities with nothing more than some hot then cold running water.
The Reaper stuff is brilliant in that regard as well.
