Congratulations!!! I have both a 401 and a 403 plus some others. LOL. I love the 403 for doing some decorative things that my 301 cannot do but the 301 is my go-to machine.
I love my 401A and use it all the time. It, as others have said, will power through most anything. Mine was bought in 1958, the year I was married and still going strong. You are going to really love it.
