For me it is not about the money at all. I would spend $100 without flinching. For me it is poison vs nonpoison. Out of 70+ animals, over 20 of them are animals the have a sensitivity to P.A.M. type products. If I have an alternative method, that is poison free and works, then why would I even want that stuff near my collection? To me the convience of P.A.M. is not worth the risk.
