Ive used old and new over the past 20 years with success on both. The big thing is what your going to use it for and how much your going to use it. You will want to make sure you can use straight blades and not just pin blades, or you will never be able to make a small inner cut. If your strapped for cash and this is a big savings, do what works for you. If its not and you need to wait a month or so, wait and go for a new one. You can get one at Menards for less than $100 and it would be modern so you would be able to do what ever you needed with it. Sometimes you can even get a factory refurbished with a warranty for a good price. Just google.
