I talked the other day to a member that has been mining for over a year, and he stated that mining is pretty much as profitable as it was 1 year ago (difficulty and price have shown a correlation, although i wouldnt trust that it will stay that way), so id say that it is still ok to mine. Plus its not that easy to buy coins everywhere, especially in smaller countries. Consider your mining rig as low-risk coin buy, given that you can always resell the hardware, so techinally id say that the "break even" point would be for 40-50% of your hardware cost, not 100% as most people suggest.
