A question for Tile Proxy users

Hello,I know this is a little off topic but I thought a Tile Proxy user may have an answer to my question. I am looking for the most up to date imagery for Mexico - particularly the Yucatan Peninsula and Isla Mujeres. Google Earth's image is pretty current but it is very bright (reflection from the sun?) I can't see any detail in the urban areas. Yahoo and Bing are not very current in that area and they don't have the building I am looking for. Are there any other(free)options out there that I can look at? I'm not looking to use it in FSX, I just want the image.Thanks for any help you may be able to provide.
