What in the world are you going to do with 60 tubes?
I have 12 and doing just fine. I dont even think there are 60 different blades to put in the tubes. Well, maybe there are but, I would be so confused about which blade to use that I would never get anything cut.
It does seem like a good price, but buying things because they are cheap weather you have a use for them or not, seems like a waste of money to me.
