Hi Ted.
I purchased my first fogger from HQ (previously Hechinger) hardware store. HQ has since gone out of business in this area. I
purchased a second one from Lowes hardeare store.
For information purposes, I plan to check Home Depot and other local hardware stores to see if they carry them. I will post my findings later.
I paid $65.00 and $68.00. I am told that some people have paid less for theirs. So, I guess that as with everything else, it pays to shop around. But for that kind of money, it is a well worth investiment. If you are careful the investiment will last you a lifetime.
Good luck.
