Some companys are worried about corruption.
Transparency International Corruption Index (CPI) is based on opinions amongst business people regarding public information. The range is 0(Highly corrupt) 10 (highly clean) Finland CPI score 9.7, UK 8.7, Austria 7.8, USA 7.7, Germany 7.3, Hungary 4.9, Lithuania 4.8, Poland 4.0, Czech 3.7, Turkey 3.2, Russia 2.7, India 2.7, Indonesia 1.9. sounds like the results of the Euro song contest.
Hope this helps for those who are taking the plunge!! SAYS IT ALL REALLY!!!

As things are at the moment I would keep things close to home. Also remember the winters can be very harsh in places like Poland & Czech lasting a good 7/8 months snow drifts airports shutting down etc, you can get fed up with it once the novelty wears off! Some of these countries are going through big transitions so tread carfully.
