cheap nylon membranes?

[rob]

For a series of experiments we need probably hundreds or even thousands
of nylon membranes (20 x 20 cm). The ones we are using currently (PALL)
cost about 

Does anybody know a cheap source for such membranes (i.e company) or a
similar kind of membrane with similar properties?
