Since you have a free electricity, it always will be profitable for you as long as your miner doesn't crash before you get ROI on it. Around that you could fins some Antminer S4 (I'll put some links below) or you could also go with two Antminer S5 if you find good deals. A reminder that it would be better to wait for the halving to go underway and let prices of miners drop after it before you go and buy since more efficient miners will come out.

I'd even be inclined to consider selling two Antminer S5 to OP depending on where he lives, because of shipping conditions. Should be ROI-able before halving and then no idea what BTC will look like then but at least he'll have profited marginally + have existing hardware.

With free electricity you are very lucky.  Past gen is getting cheaper and cheaper.   I would look at S5, SP20, Avalon 4.1 myself if I had free electricity and looking short term.

Long term A6 or S7.  They just are a lot more efficient which means even more profit (hopefully).  But they cost more then past gen's.  So kinda depends on your game plan.

i want to remind you that even with free electricity one s5 for example is doing only $45 a months right now, so 5 months roi if you buy two with 1 btc(i dunno if they are that cheap last time they were priced at $300)

and this without accounting the increase diff and the halving, that will be here before the 5 months roi....yeah in the end you will roi with free electricity, but the time needed will make the effort kinda pointless...

This is interesting information. I have an S5 and last year was a better mining year. You are correct that the S5 makes roughly 45 per month and started to feel a change from 90 somewhere in July of 2015. I have a bitcoin and some eth and think it is better to buy and sell them in an exchange. Mining a good old altcoin is much better than BTC with these machines. Buy a couple of usb miner like a compac or the new futurbit scrypt miner. That way while you are trading shares you can still mine freely.
