Germany (read: Berlin) is surprisingly affordable, but hold off until the springtime, unless you're looking to better understand how your laptops perform in sub-zero temperatures. Berliners also pretty universally speak English, and there's a decent-sized startup community there as well.
You could come to Tokyo, where I live. Don't. It's ruinously expensive. But you could go to a lesser-visited part of Japan for a not-unreasonable amount of money, and while people's English skills are lacking here, the public infrastructure is fantastic.
Taiwan is like Japan, but with better food and cheaper living costs, but without as much infrastructure. Still one of my favorite countries in Asia, though. If you decide on Asia, avoid the summer at all costs, because the entire region turns into a gigantic sauna.
