In looking at the NE Cheesemaking website, the disposable cheesecloth looks much more fragile than plyban is.
I ordered plyban from Hoegger's last year and absolutely loved it. Then, when my cow was dry (so not making cheese), I had put it away in a plastic bag for this year's cheesemaking. Well, in a moment of udder (er, utter) stupidity, when I was cleaning out my cupboard, I looked at that "bag of plastic bags" and decided I didn't need to be so cheap as to "save plastic bags" and threw it away.
Two months later, when I was frantically (sp?) trying to find my plyban, it finally dawned on me that I threw it away. I felt like such a fool.
I need to order more, just haven't gotten around to it yet. I'd be more driven to it if I were having trouble with my cheese sticking to the cloth, but haven't had that problem lately.
