On the whole, I didn't see it as that much cheaper than the US. At least, not much cheaper than the cost of living where I resided at the time. (AZ)
It was OK. I didn't fall in love with the place but enjoyed it enough.
A lot has changed in the US in 7 years though. In particular, for me, the over crowding everywhere. I may have to revisit the idea.
Heat. Mosquitos. Not sure I could get past those two things.
