May be i´m wrong but i think more than look for new countries we rather look for regions. For instance , the center and north of Portugal will receive from EU about 70% of 21.5 billions euros that are coming to Portugal from 2008 until 2013(10 million per day approximately). The prices are now in center of portugal less than half when compared with Lisbon or Algarve. Viseu is considered the best portuguese city to live and one of the best in Europe. But in a couple years the prices will be much higher.
For these reasons i think center of Portugal can also be considered a good region for investors

Best regards
