The PACKS metatype costs threw me at first glance too, but they are actually fairly simple. They take the base metatype cost, and you get the Attribute increases that go with it. Just like build points so far. Where the difference comes in, is that atttributes that are capped lower are actual penalties, which get subtracted from the base metatype cost. So Fastjack did it correctly. The pixie, for example, costs 35 points, and has -60 points in Attribute penalties, for a result of -25. Xapiri Thëpë cost the full 45 points, because they have no negative modifiers to bring that cost down.
One thing I would add is that the infected and some of the innately magical types would not qualify for any of the technomancer kits, since they can not take the technomancer quality.
