My absolute favorite is the recycled Corn Cob pellets. They look a lot like the wood pellets but in my experience, with care and following directions, they last longer. They fluff up with moisture and you just scoop out the poop and then "stir" what's left. I stir every day, but you can get by with every other day...just pull it all into a pile (a shovel or strong metal rake works best) then smooth it back out. When weather is hotter I also add Sweet PDZ to it every couple of days. The downside... a lot of people don't like it because it looks and acts like dirt so if your horse lays in it they get pretty darn dusty.
