Wow that Luffy model looks really good! I'm not really a One Piece fan, but that is one of the best Bandai model kits I've ever seen. Personally I hate the look of the Goku MG models because of the face, but it looks like they nailed it with this one.
I thought with so many Power Ranger fans you might be interested in this. The SDCC Samurai set is still available at Collec-Toys for $229.99, ToyArena for $219.99, BBTS for $224.99 and Anime Island for $246.96.
It just seems to me, especially here, that Power Rangers Samurai is the biggest successor to the original MMPR. I think it is because Saban got back the rights. You can't go into a store here without seeing some Samurai merchandise.
