Well,playing with cars is expensive. But on the positive side changing over to DOT 5 will save you money in the long run.I have been using it in all my cars since the mid 90's and never had any kind of rust issues inside any of the wheel cylinders or masters since .So yes,it costs 25 bucks a QT but that's it . I ran it in my wife's Valiant that she used for commuting to work and never changed it or added a drop to it in the 13 years she drove that thing and when I parted it out the insides of the wheel cylinders were clean and shiny not all full of crap like with DOT 3 . You get what you pay for.
