We used to see those ads a lot, however there has been no home ec in Nebraska for years, so how could they be school machines??? I think they are overpriced cheap machines liquidated because they are models that didn't sell or were lemons and I wouldn't buy one for all the tea in China. I would much rather buy a high model used machine than one of those. These sellers will be there one day only and when they are gone, they're gone, no way to return and no one to complain to.
