yes, it's still cheaper - I mean cheaper than Western Europe, but the prices are smilar to US prices - only housing is much cheaper and that's the difference.
Latvia, Estonia, Lithuenia, Poland, Czech, Slovakia, Hungary are the best to visit May to September after that you never know with the weather. No worries with a language barrier, people speak English no problem (I mean people under 40 some, under 30 almost everyone)...
Good luck!
