Does anybody know of any good resource vendors on hazi? I know of a couple that deal with high quality or rare stuff, but i'm having difficulty finding one that covers the stuff in between grind quality and super quality. I've been looking for desh copper, iroluun reactive gas, doonium iron, and polonium iron for about a week. My supply is getting low and I need to restock. Please let me know if you know of any good ones. Thanks.
