Looking to buy a rig or 2 very soon. Seeing a lot of resellers. Im looking to invest 4-6k in a miner. For obvious reasons, Im very nervous to give my money to some company in China. Ive contacted several of them, and they all seem to be very helpful. So, that doesn't answer my question. Ive asked questions about types of PSUs, trump tariffs, shipping speed, etc, and they all have "the right answer..." The least eager of the companies I contacted are the manufacturers of the miners.

I've googled, and this seems to be the most helpful community for this question. I can not seem to find another good source for this question.

Has anyone dealt with any of these companies?
Crypto Drilling
Miner Bros
Mining Store 5111
Coin Mining Central

Any others that I didn't list that people have dealt with?
