I already own that Sekirei set, I'm surprised you bought Eureka 7 , I would have though you make have waited for Anime Limited release @Grav
Yeah about that, I picked up Astral Ocean Part 1 back in October 2013 and the original Eureka 7 Part 1 back in April 2014 so it's been quite a while.
But yes I will double-dip for the UK Ultimate Edition as I really enjoyed what I've watched so far (plus having Region B discs isn't an issue).
