Cadillac Blower motor

I have a 1997 Cadillac Seville with 117,000 miles. The blower motor went completely out. Trying to decide if I should bite the bullet and buy a new blower or look for a used one. I’ve heard they have a tendency to go out so do I take a chance on used or just spend the money for a new one now. I live in Minnesota and need it.
