I love the model overall but I'm really annoyed that it's store anniversary only. While I'm glad it's not just another fairly generic space marine, putting such a cool unique model (especially when it's the only ordo without a plastic one) sucks.
Things like the cryptek are perfect, a cool interesting model but that's still got alternatives. Although I really wish that they'd look at making models like this available regularly, maybe a general anniversary where they can be made to order once a year.
As for why this is limited to anniversary, maybe there's something unusual about it that got it vetoed, like the termie chaplain from a while back that had the crozius clip through his wrist.
