Hmmmm, i'm not sure about this one. On one hand, it'd be a cool mini and i'm sure itd paint up well. On the other hand, i'm not sure when i'd ever use it. After all, in the games i've played, no ones had a reason to shell out for a standard holocaust judge for support, let alone an entire manta. Unless you are looking at moving away from skirmish rules and moving into mass battles, i just cant see them being used as much.
I'm not sure what the current state of materials are at the moment, a lot of companies seem to be focusing on resin at the moment. My only knowledge of resin minis is forgeworld, and frankly, i just wouldnt have the money to go there. If plastic was a cheaper option, i'd say go for that, even if the quality isnt as crisp. I've seen the 40K Baneblade thats standard plastic which is around about £50-£60 if you shop about, and seems every bit as nice as the forgeworld one, from the pics anyway. Something like that, i'd happily pay around £40-£50 for a manta, even if it wasn't really going to see the battlefield.
I do love the fact that the Dredd range is pushing forward, mind you. But i think the appealing thing about it is the size. A gang box set for £20 and your not only off, but you have enough minis to try a few options with and a few to add to your gang as it grows. A judge team can start for less than a tenner. That's just the way i see it.
