I have worn out many a mix bag, and they all break at the zipper. You can use the 220, but you have to go by hand. I use a camping washer, and you can't put that mess in it without that bag.
As for bags, the cheaper the crappier, but I have a set from resinextractor dot com that are two years old now. sixty dollars delivered in the us. The only thing is that the bags are solid material all the way to the bottom, so the drain is slow.
I find it funny how lazy we get, one of my friends is way older, and he's been making hash with a bucket, a spoon, and some coffee filters for like twenty years. Now, he complains when any part of the process holds him up.
