I didn't have to look very far past my nose to find this in the ziplock aisle at my local chain grocer.

It was $4. A box of quart bags was $3. Works like a champ, for $7. My system is perfect. Buy from farmhousebrewingsupply.com They come in 4oz, bags. I cut the corner of bag upon first use, and two of those bags fit perfect in a quart ziplock bag. you can see the labels through the ziplock bag, so you don't have to open it to see what hops are in there.
sealing takes 10 seconds, and I figure, if and when it breaks, I'm in for another $4.
screw those big fancy machines.. waste of time and money if you're just sealing hops.. those are for game hunters.
