Very pleased with the Singer 201-2 I purchased on ebay. The seller packed it extremely well for me, double-boxed w/ lots of batting and a clean old blanket for padding. She had tried to sell as "pick-up only" in a large cabinet. After I explained I just wanted the machine - already have the old "art deco" writing table/cabinet - she sold it to me, kept the cabinet to use for herself.
She even sent attachments and a fistful of notions 2 weeks later when she found them in the seat that went with the cabinet.
Her hubby accidently cut the cord taking it out of the cabinet, so she replaced that and had it serviced while it was in the shop - overall, I couldn't be happier.
Good luck in your search.
Make sure your seller has stellar feedback ratings, insures the item and is instructed to double-box and pad very well, especially around knobs and presser foot arm.
