For me also a big question of:
-Quality, price, how is this guy ( is he authentic,cordially,honest ect. or is he the opposite),kind of material which will be used ( ABS , HDPE ect.)
-Do i want to give my $$ to someone i never heard befor ( and i'm sure this parts will be in a higher pricerange)
-Will this armor ever be finished so as we all belive it ( something bad can always happen)
-Waiting time ( bad example: only think on TE )
-limitied runs of parts
ect...
