Those RMPX SW1500's have spent most of their life here in Dallas. If I was still modeling the TRE in N, (or if they would release them in Z) I would be all over them. Still might have to get one. Been needing a mech anyway.
EDIT: Interesting that the artwork seems to indicate they are using the same gray as on the SP's for the trucks/fuel tank/et al. I think they should be black. The other thing is, I can't use this particular mech since it is an ex-SP so the trucks area all wrong for me....drats.
