I just have the 512x512 head piece, with art ofc.
I've estimated about a rought ammount of 500k tc needed for a full 512x512, 2 joints and a set ideea.
Yeah 512 is really expensive :V i still havent gotten the arms but i have the legs. I think the full 512 without joints is around 200-300k i might be wrong tho :V i know Swaves is selling full 512 he might sell it for cheaper then the market if your lookin
