magicmanag on mostly alphabay (on nucleus too) seems to be more established but he's FE, lives in canada, is on vacation mode rn and will be back when escrow funds are reduced. Magnusx on nucleus is new and he's escrow, lives in britain, seems to have good reviews, although I kind of think the username makes him sound a bit dodgy. Prices seem about the same, i think. I live 'down under' so I have less vendors to choose from, would ordering from canada be faster in the post?
Never get bent on fent.
