Wiz - thanks for the advice - did not think about brining the leather with me to test (honestly I am real new at this).
I am now also considering a 7yr old Consew 206RB5 with its stock clutch motor for 850.00 and a PFAFF 1545 (dont know how old it is yet or motor or needles etc., ) for 750.00.
They are both in working condition. My question is ....... which should I focus on? The Juki LU-563 I originally inquired about is definitely older - about 20 yrs old and it's been dismounted from its table - so I am considering it less.
