No miner at the moment will get you ROI, you will operate in the RED for the miner's and your lifetime. And the worse thing you can do is start cloud mining. At least you can resell hardware miners for a decent price after you're done with them.
If you just want to start mining to say you're mining and be one of the cool guys, to learn about mining as a hobby for education and fun, while generating some BTC for yourself, and don't care if you break even or not, get one of these:
