i think you better wait a bit for others to respond back. i don't remember where i read about this place but there had been problems in the past before i came here. but i don't know if that is old news because on the other diecast forums i'm following there do not appear to be any issues.
I got some of my new releases from him. Even now, I still have some preorder from him. He's a bit slow in response but my order always arrive safely. I'm aware that he was banned, but the problem that got him banned happened before I got active here, so I don't know what that was about nor can I comment. But so far I haven't got any problem with him.
His facebook page, as far as I know, is the one on the #2 post (Screetoy Jakarta). The one on the referred thread above (Screetoy Concept), I don't know about that one.
