Bandai holds the license for frontier mecha in 1/100, 1/72 and 1/60 scale... Yamato has no license to make frontier toys, but there is some light at the end of the tunnel, since it appears that Yamato has gotten a Macross 7 license that was previously locked by Bandai, so maybe in 10-15 years, yamato will make frontier toys........yes, that's sad....
1/100 frontier line toys are small, not perfect transformation, requiring you to swap several parts for transformation, a big ugly, around 40USD
1/72 are scale models, perfect transformation, gorgeous, it can be assembled without any gluing or painting and get pretty good results, also around 30 to 40 USD
1/60 are perfect transformation also, ugly as sin, apparently Bandai made some sacrifices to make it PT and durable, around 200USD, not worth it
this are your only options for frontier mecha, if you want resin figures or characters, I don't know, search for the threads of everyone who doesn't have a gf waking off to klan and disturbing comments of people wanting a boobed mousepad of alto... ?¿¿?!2&"! ????
