Thank you for the valuable information... I will take a look into a hosted space in a data centre but I think it could still be more than the monthly return.
I would defenately advice against running a miner if you pay 17 cents/Kwu... That was the point of my post. I took the bestcase scenario, and it would still take about a year to ROI if everything else stayed status-quo (and we know for sure that this will not happen, the block reward is due to halve in about 6 months?, the diff is steadily rising, the BTC price is having a little dip ATM,...).
Also, the warranty period for bitmain products is 90 days... That's about 25% of the time you'll need to ROI in the imaginary best case scenario...
I would personally say the limit for profitable mining would be around 6-7 cents...

@7 cents, it would take about 5-6 months to ROI at current conditions. That way you should have reached break-even around the time the block halving is happening. It's still risky, but acceptable.
