Hello, I plan on building a relatively small mining rig with ~48 mh/s
It would cost me around 440 euros, and I theorically should earn around 4 euros per day.
Do you think it's worth considering difficulty is constantly rising ? Will I ever get a ROI ?
I had a bad experience with a 500$ asic miner that I bought like 15 days before btc value went from 800 to 300$ ^^
Thanks

As you specify the cost of hardware in Euros I assume you live in an area where energy cost is high(like I do). Give the current difficulty and ETH price mining can be profitable for a couple of months even with a higher energy cost. However, if it's "too" profitable, more people will mine ethereum and the difficulty will increase at a faster rate, making it profitable only if the energy cost is low.
Since I had the same questions I created a profitability calculator. You can try it here: http://cryptowizzard.github.io/eth-mining-calculator/
Any feedback would be appreciated.
When you posted this, January 29 of 2016, ETH was worth about $2.47/ea. (USD)
You had about $447USD dedicated to building a miner.
If you would have just bought $447 worth of Ether, you'd have had just over 180 Ether all to yourself.
180 Ether at the going rate today (June 14, 2016) is valued at $18.73 USD each, and it's been going up almost a buck per day for the past week it seems like.
Your $447USD investment would have turned into $3371.40 over the course of 4.5 months.
Long story short, when in doubt - just buy as many coins as you can.
I also added 2 more pages with a list of available motherboards and graphics cards for mining.
