Coincidentally, my same friend has that one as well. He likes it, but I haven't had much experience with it myself. Looks cool though. I can't speak either way for the NC Star one, but I'd say either of the two that my friend has would be worth it. Bear in mind, I've only seen it while it was functioning well. I don't own any of the scopes linked, so I don't know about any kinks or quirks that an owner would know about.
