I have always loved the retro-feel and simplicity to the Mazinger and Shin Getter series of bots and it seems that the simplicity can stillbe transformd into something whih is both Hyper-detailed and super articulated; these robots don't come cheap and are approx. 100GBP. It could be due to the fact that the toy-legend "Professor Robo" Taku Sato has passed away making his designs even more collectible.

Toybot Studios has more brilliant images of both robots and details of where you can buy them.
