I'd probably base myself in Bali. Good exchange rate, can get away with anything as long as you're prepared to pay for it and the lifestyle is beautiful (None of this Kuta rubbish either). I'll be looking for a holiday house there in the next year or so.
Second to that, Brazil. My Mrs is from the south near the Argentinian border, but I'd rather go north or at worst Florianopilis.
