I've been using a nylon net that fits over the rim of a primary bucket. You can get them at brew stores or on-line. Mine are 14 years and still going strong.
I pour the hot wort throught them and sparge ANYTHING that's captured in there. Works like a charm every time.
Just be sure to hold them in place with 6 clip-on clothes pins so the weight of the water and hops doesn't pull the wort into the bucket. Trust me on this one.
