Blades are the cheapest part of scrolling, My thoughts are if you c an't afford a .$25 cent blade then you need to find a different hobby. Perhaps I am fortunate enough to be able to afford blades, so I don't even give it a thought about what one costs. I don't mean to offend you but there are costs to all hobbies and some of them are very expensive .Don't worry about the cost, just enjoy what you are doing.
