Will other consumables from other manufacturers work?The cost through Home Depot is like $89 for a set of ten. This seems just a bit expensive. I have seen other makes cost a lot less for the same cost.Note, Home Depot offers a three year warranty for $80 .Anyway this appears to bethe avenue that I am headed.
