Best Tea Ball?

I started with a cheap one from the store (just a simple clamp) and it warped and spills leaves now. I also tried two by teavana and I hate both of them. I need one with very fine mesh, a good lid, and a lot of space. Anyone have one they really like? EDIT:I used to use nothing at all, but cleaning was a hassle and if I wanted to use my teapot warmer and dispense cups of tea at my leisure, there was no way to remove the leaves and keep the tea from turning bitter. I loved my old tea ball, but it just leaks too much now and I wanted something with a better mesh, too. Also, I prefer to avoid plastic and wasting paper for tea bags.
