My neighbors switched to sand and after watching them backwash and haul 50 bags of sand, I will stick with my DE. Especially since I have never had problems with it and I have the routine down to an art.

50 bags of sand? Wha???? No way. :o
My above ground pool (10K gallon) takes 2-4 bags. (they are 50 lbs each) at a cost of $8.50 (I just checked the prices with my local dealer). It last 5-7 years.
The largest comercial sand filters I've seen take 700 pounds of sand, (which would be 15 bags). Most above ground pools take 150-200lbs of sand.
Sand is the easisest of the all the mediums to use, and very affordable.
DE is more efficent at trapping particulate matter, but requires more maintinece. How much DE do you use each year? how much does it cost?

50 bags of sand...............50# bags of sand........BAH, what's the difference.
Drew, the difference is a TYPO ;D ;D ;D ;D ;D ;D

that's a pretty significant typo (and that's comming from the king of typos).
Plus, Bonnie NEVER makes a typo. :-/

DE is classified as hazardous waste in some localities thus disposal becomes an issue in those localities (only when you get caught). Supposedly this is increasing, how much so I don't know so it may never be an issue where you live. Just something to be aware of. I do know that DE filters do the best job of filtering, followed by cartridges and then sand. Sand filters with new mediums such as zeobrite come close to DE filtration. Then there are also folks who add a little DE to their sand filters to increase efficiency.

Tony, I looked up DE on line and I couldn't find anything like that. It looks like a natural substance that has multiple uses. As I said, once it rains, my DE is asorbed into the grass and you can't even tell it was there. Now I have to know why it would be considered hazardous waste because I am dumping it out near my well... :-/
