The best place to get a review that is honest is PatternReview.com, they are all put there by the members of that group. Although I do not own a Singer I sure hate to hear folks cutting Singer down. And yes probably their quality is not like it was 30years go, but... you never know unless you try.
I have a Kenmore / Janome 19233 that I love. I bought it off Craigs list about 5mos ago. It is a fantastic machine. In fact I am buying a new Babylock, well a floor model, and I am still wondering about keeping my Kenmore. I wanted a machine with a bigger harp opening, is the only reason I am replacing it.
Also alot of good machines are being traded in at the moment because of the newer machines that just came out. You might check your local dealer for a good used one. There are also some good buys on floor models.
