You will love owning one. When I was in the mattress business I had about 40 commerical sewing machines. I still have about a half dozen in storage and one that is still crated in the computer room.
One machine that is one tough bird is the Singer 111w series. I have sewn 7 layers of heavy leather with those machines. It will do two layers of vinyl but that is ablit as light as it will go. I used to find them floating around cheap.
