I bought the first one when the plastic model first came out and gave it a TL Heavy bolter. They took that option out of the next edition, so I bought another one and made it a long range dread. The third one I bought because I wanted to play with magnets. I originally painted them all as Salamanders, but unfortunately the paint job sucked. I didn't see the point in repainting one and not the others, so I redid them all and magnetized the weapon arms of the first two.
Now I just have to put the finishing touches on a few Rhino's and I should have a 1500 point SM army ready to go.
