AT, if what you're looking for is an American lifestyle at a cheaper price, I think you're doing yourself and your prospective host countries a disservice. Part of the joy of being an expat is adapting to the differences of your new home, and a lot of this will mean NOT living an American lifestyle. It will mean living more like the people in the country you select live. In Ecuador you can have a very comfortable middle-class lifestyle for much less than you can in the States, but remember that the Ecuadorean middle class is different in behavior, attitudes and expenditures than the American middle class. If you want a "rich" lifestyle, it'll cost you in Ecuador just as it does here, though differently (for example, you can be "rich" here and not feel OBLIGATED to have armed security guards at your home, which is encircled with a 7-foot masonry wall topped by broken glass and/or razor wire. You should see the fortresses some people live in in Quito, and not just in the dicey neighborhoods, either).
If the two worlds were the same, everyone would be moving to Ecuador, or Panama, or Buenos Aires to enjoy a U.S. lifestyle for less. Fact is, they aren't, and the lifestyles are different, too.
Just something to keep in mind as you prepare for leaving. Culture shock is real and can be very difficult to deal with. I'm especially concerned about your soon-to-be wife -- leaving her home in the Phillipines, getting married, and moving to a very different climate and country would be very difficult, and I don't know if there's a sizable Filipino expat community in Ecuador for her to bond with.
