He will provide a quality product in a short time. There are some other producers but none that will be as fast and reliable as Asok. He has sale threads on TDH just search "Asok" and it will show up. If you are looking for a finished one...I am painting one up right now that I will be selling when I get done.
Bobamaker makes very good Jango Fett helmets. Visit his homepage at bobamaker . Maybe he is not as cheap as others, but the quality of his helmets is awesome.
