A lot of people agree that the body is useless once we die. That is doesn't serve a purpose anymore and that even if we are cremated it won't stop God from being able to ressurect our bodies to perfection in the end.
In my mind, this is like saying it's okay to get tattos and body piercings, because our bodies will be resurrected to perfection.
The quote provided earlier in the thread states "Church leaders have counseled that only in unusual circumstances or where required by law should cremation take place." (Ensign, Aug 1991, "I have a Question".) This information isn't just the opinion of the author of the quote, it comes from the church's General Handbook of Instructions from 1989. However, new editions of the handbook have been recently released, so perhaps the leaders have changed this information.
In the end it is ultimately up to the individual to deside. But I don't think we should take counsel from our leaders lightly and lable it as a "suggestion" or "encouragment".
