I keep looking to purchase a used heavy duty sewing machine for doing canvas work. I've sewn all my life, have three machines already and yes....want one more!I look on Ebay, Craigslist, newspapers and contact commercial machine stores looking for a bargain. Nothing as of yet.Does anyone know someone wanting to sell their machine for a VERY reasonable price? I could purchase a Sailrite but don't want to spend 500 plus right now when that money could go towards an outboard motor for an inflatable or kayak.The crutial feature I'm looking for is a machine that has a walking foot and can sew at least 8 MM stitching. It can have zig zag (would be nice)but basics for leather/canvas is ideal.Thanks all,Laurie
