I have tried Alibaba in the past order for miners for about $10K and had good success. Make sure you have a good rating on the company that you are buying from.
What payment method did you choose? Can you give us the name of the seller?
I guess some extra info would be greatly appreciated by alot of people here.
I used Credit Card on that transaction. I do not remember the name of the company. It was about a year ago.
