They're very nice models, but as Alpharius mentioned before backing people should take some time to review the original
KS which funded in December of 2012 and is still not fully completed based on the posts of the last 3-4 pages of the thread here and the most recent comments on the campaign itself.

There are also pictures of what I assume are the production casts of the models shown in the most
recent update to the old campaign (yesterday) which prospective backers should check out since they do appear well-cast. It all looks impressive and much of the actual work would appear to be done, but past behavior makes me far too leery of backing it in a
KS format. That said, the ask for a single model is likely within most people's reasonable risk range (I think most of us spend more on a bad night out) so folks might be more comfortable with small pledges; they do not seem to be a scam company like some projects so you will (probably) get your stuff and that stuff will (probably) be good, but they have shown they can have more than their fair share of delays. As Kickstarter is always caveat emptor I wanted to make sure others knew what they buying into rather than have more irate people waiting owing to a lack of due diligence which is just bad for backers and creators alike. Informed decisions and all that.
