As to the Davis, how will I know if the shuttle is complete? I have never seen a Davis in person and the seller is a non-sewer so there's no help there. Also, are the Boye #20 needles available thru EBay or some other source. I know I've seen the #10's on Ebay but can't recall any #20's. I knew you ladies would be able to help me out. Thanks in advance for any and all help. ~ Chris
