I have a working, older but perfectly serviceable Sailrite Ultrafeed LSZ1 ZigZag walking foot machine available. Comes with power and pedal cord, case, Monster wheel, 3 bobbins, a few needles and the thread dispenser arm and base. Very powerful machine....I have sewn a very large 40 mil StrataGlass enclosure, helm and fender covers, upholstery repairs, handrail and bulwark covers flagstaff covers etc....not much it can't sew.
It is currently located in Stuart Florida, but can be picked up in Toronto area mid April. $500 USD firm.
PM if of interest
