Can't say I know of any that are Official distributors and as is also true with Bitmain, Innosilicon, and Btmicro (Whatsminers), you REALLY need to buy through any distributors that those manufacturers list on their websites.

Why? Primary reason is that the miner warranty is valid only with the entity that 1st purchased it from the manufacturer. That means that when buying from some random 3rd party all warranty service MUST be handled through who you bought it from. That is most likely be a big problem...
