I have a 328K. It was my very first machine -- my husband bought it for me at Christmas, the first year we were married (1963). It's a real workhorse of a machine -- I've used mine heavily, for anything from upholstery cloth to drapes, to maternity clothing, to baby dresses, gowns, suits, etc. I've never had a major repair. It was new when I got it, the motor is still good. It is a noisy machine, but I've gotten used to that over the past 50+ years! Mine is tan. I'm very happy with mine. Once you get the 328K going, you'll either love it or hate it -- there doesn't seem to be any "in between"! The 328K doesn't have all the bells and whistles, but it has and continues to sew very well!
