Looking for Mining Hardware Under $600

The title pretty much sums it up.

If you're talking about hardware that will actually make you money no chance. But if you just wanna try your luck with solo mining, there's this link... you can check it out. Just so you know, results vary.

I've seen the S9 priced around 580 with a PSU. It could be profitable if your electricity costs are low enough. I found a listing on eBay. No clue if the seller’s legit or if the device works. But, just to break it down: It makes about 38 cents per TH and around 4.94 bucks a day. If your power is 10 cents per kWh, it'll cost you about 3.12 a day to run, so that's roughly 1.82 profit. But at 20 cents, it costs you 6.24, leading to a loss of about 1.30. Do the math based on your rates.
