I just ordered a gallon of the froggy freezin juice for $30 shipped off of ebay. I was going to buy the 2.5 gallon, but last year I opened up my froggy's leftover from the year before and it had mold in it. I was afraid if I bought a full 2.5 gallon and didn't use it all, which I am pretty sure I wont, it will be wasted by the following year. I think a gallon in the v960 set at 40% or so ratio output should last for the 3 or 4 hours I am going to run it on the big night. I also still have a gallon of the black label which I don't think is nearly as good, but we'll see.
I am curious now too, what the big fuss is. I'll try both in my "cheap" fogger as well as the v960 and see which is thicker, lasts longer, etc.
