Tea Strainer What do you use?

What do you guys use for a tea strainer? I used to use the cloth bags from Teavanna but don't really shop there anymore. I think they work pretty good but alot of times I would see particles from the bag in my cup of tea and thats not my cup of tea. I tried a mesh ball that encloses the tea but it broke after a couple cups. I might try reusable bags next from Earthfare. Anybody use that tea infusion system Teavanna sells?
