Dan,

I am sure there is an industrial sewing machine shop within 10 miles of you in Orange County. You are looking for a Consew or Singer straight stitch walking foot with a motor, table, bobbin winder and thread stand. Used and sewn off with V138 thread and a #22 needle. These machines are easier to come by then zig-zag machines dialed up for sails. Stay away from the oil resevior models. Expect to pay $600. Look on Craig's List as well. These machines hold their value. You'll be able to sew everything except sails with it.
