Ok, is Bandai's Soul of Chojikin line worth the money, because I wanted to pick up Poseiden, Mangzinger/ Mazinkaiser one day and need to know like a year or so in advance (waiting until I have a job that can cover those die-cast things, or next tax return)
Firstly, its Soul of Chogokin and secondly there is no Mazinkaiser in this line and there might never ever be one.
Only if you were a fan of the bots and not buying them on impulse. They're the best rendition of old school mecha and new ones but they can be a pretty expensive hobby.
