on many sites I should order in large numbers but I only want 1 or 2 miners..BTCBTC
amazon.com provides BTC miners NO NO and NO. Don't buy on Amazon or Ebay, you will pay way too much.
Check here on the market section for a used btc miner. Like Hazir said, you need to understand that ROI is currently really hard to get. Except if you have a really good electricity price.
Check for a S5, a SP20 or a Avalon4.1 they are the best miners right now.
Have you bought from anyone on here? Can you recommend anyone I can trust? How would I know to trust someone? When I buy on eBay I can get a pretty good price and I read hundreds of real reviews from independent people. If something is wrong, I know who they are and can dispute the transaction, etc.
