Instead of those overpriced grain bags, I really like the paint strainer bags you can buy in 2-packs from Home Depot or Lowes. It costs $2-$3 for two of them.
What I like to do is layer two of them on the pot. The first one I use to mash the grains, and the second stays in when I pull the grains out, and receives my hops additions when I bring it to a boil.
