Me too. Actually 4 teenagers (girls). I'll be the first to tell you that other than the holidays when I may cram in a few batches, I get to make a run about every other month. Actually, my last batch (and first ortho) made in June is about 1/2 used. Checked it last week and it hasn't grown fur so it should still be good. Right now I don't have time to coat the rest of it and still two rolls to shoot up from the last coating. My batches are about 150ml each. I have made single jet and double jet runs and while I haven't actually achieved VAg control, I can accurately measure and track VAg and rudimentary control is within my grasp. That means it isn't hard. There is noting in my setup other than the silver wire that didn't come from a local hardware store. The silver wire I bought online.
still have three teenagers in the house and a job.
