Yes, I consider myself very lucky for having found this used miner for this low price (0.55 BTC, including shipping). It was also fortunate that it had two built-in PSU's, so I didn't have to invest in one. And that I don't pay anything extra for the electricity I consume – it's included in my (flat) monthly rent. All of these makes me hopeful that it should be possible to recover my initial investment and then make some money on top of it.
