Does anyone know of a good, clean and cheap dentist anywhere in the Yucatan Peninsula Mexico?

I am working in and around the states of Quintana Roo and Yucatan, Mexico and am in need of a really good but cheap dentist in the area that is both clean and fairly cheap. I may be in need of two root canals and a crown so I want to find someone that is really quite good. Any suggestions would be greatly appreciated.
