Hey fellow /toy/ soldiers, I need some suggestions here.
I was looking at diecast mecha the other day and I noticed there are a tons of remakes and reissues and above all the same toy being made by different makers 5 times over (colors falling under remakes in my book).

My problem here being is that I'm trying to find diecast mecha (mostly super robots like GGG, Getter, Mazinger etc.) and I'm being overwhelmed by the giant line of the stuff.

TL;DR
What are good lines/reissues and what should I pay attention for when looking for a new addition to my diecast robot family?
