Seems kinda pricey for what it is. Usually you can get a nylon bag for cheap at your LHBS. I'm not sure what others have to say about this, but I usually use cheese cloth (steamed first to sterilize). It's dirt cheap and can go in the composter when done!
If you did want something stainless, it might be cheaper to go with a few tea-infusion balls from your grocery store? I think they sell for around $3 CAD near my house.
