I saw all kinds of places for sale all over Ecuador on this website:

Most of the sales are by owners. There is another international real estate site as well that has alot of Ecuadorian Real Estate (sale by owners):
www.escapeartist.com
If you have Ecuadorian friends to help you check everything out, and you have a good lawyer to help, you may get some good prices on good places, and people here will go down in price. Bargaining here is part of the "local real eatate dance." I actually saw some very good prices on some of the places.
