Great idea. I use plastic trash cans with holes drilled in the sides (not top) because I had them. You can keep your leaves and dead, brown grass to layer over each adding of kitchen scraps. I turn it with a big hook screwed into the end of a broken shovel handle. In the spring I dump and toss it all together and let it sit for another month without adding anything to that container.
The barrel composters are the most useful, larger ones are easier and worth it if you have a large garden or family. Turn regularly, but you need to fill it full, then compost it, so you have to have something else for the periodic scraps until the first load is done.
Since I have winter and container garden, I can't just add scraps directly to the garden, so composting is my option. Compost improves my veggies noticably, so it's worth it to me.
