Hey Rob, unfortunately Anovos is the only mfg given a license to make FOTK armor. Everyone else could be shut down by the mouse at a moments notice. That said, as you've already discovered there are a few mfgs out there that make the armor, however only one that I'm aware of, Anovos, given access to the movie suit to replicate.
KB and the rest make killer armor but I'm not exactly certain on the % of accuracy, heck IMHO Anovos is maybe 85-90% accurate.
Back to your question, rolling the dice. Wait for an Anovos kit to show up, hopefully without any issues, or go with another MFG. Tough decision none the less.
