I Love Industrial Sewing Machines

I came across this video from another sewing blog.  Apparently this guy (Roy Jeans) is a one person show, he has some nice, old industrial mechanical sewing machines.  They are great and I love seeing them in action.  Wish I had one of each but they are so heavy and take up so much space in a home.  I wonder how many home sewists have industrial sewing machines at home.  Do you?
