Incognito/private browsing + going through DuckDuckGo (even for Google queries, with !g prefix) works for me. (Edit to add since I can't reply: going through DDG avoids Google redirecting to country-specific variation).
Somewhere, I think even on HN, I was taught about google.com/ncr - which should solve that problem (being in Country A and arriving on the localized, unreadable landing page) once and for all.
That said: I've DDG as my homepage and I'm a happy user.
Whit, what? Doesn't going through DDG with !g not just redirect to google, where your normal filter will be applied (private browsing notwithstanding)...
