I'm Canadian and I moved to SE Asia a little while ago for trading (and the weather of course). I moved first to Singapore but man is that city boring! I moved to Bangkok about a year ago and so far I've had a great time. It is not so cheap if you want to live a good life but not so expensive either (you can do great on 5000-6000 USD a month, more is of course recommended), internet access is certainly ok for trading, girls are hot, weather is great, food is great, the city is very well connected by air to almost everywhere in the world (I travel a lot) and you are only a very short flight away from some of the best beaches in the world. My trading is all corporate and based offshore so no taxes anywhere I go and the sale tax here is only about 7%.
All in all I do recommend Bangkok to anyone who likes to party, eat great Asian food and loves warm (very) weather.
