True that, actually watching these posts and seeing some of this stuff again is bringing back longing memories, not enough to start out collecting it again, but I am glad that the modern lines are getting more and more love these days and great to see stuff popping up.
As for cost the slave 1 along with the other 'display' vehicles from that line and the preceding power of the Jedi line always commanded a premium, I would guess you are into three figures for them now, I think they were 50ish rrp back in the day to begin with.
