Look at the picture below, picture gotten from Sheng Tai Toys Website:
It seems that the bigger/fatter the Gundam, the higher the price. Freakin’ hell that Virtue cost about S$15 (Singapore dollar, BTW). Hell that size does matter when it comes to toys, hehe~
Exia cost about S$12, Kyrios and Dynames cost about S$14 (What? Are they twin mecha or what?). Virtue is only available in December 2007 to Singaporeans who wants to buy them. The other models are now available.
