The "Casual Tier" will be a bang for your buck! It contains all of the past models released -- but if you're one that cannot wait for the latest models to get to "Casual" I'd recommend either the "Early Adopter" or "Collector" Tiers which will also grant you access to the #workbench channel on Discord for sneak peeks of what projects are currently WIP! Higher Tiers above aforementioned grants you to request a model that will be put into consideration, and so on =).
