I am not recomending a sewing machine, because I only have old ones. But, stay away from the newer singers, unless it is the XL-Quatam or whatever its called. I do not recomend Computerized because while I have never sewed on one, they are very expensive to repair if you are sewing and there is a power outage you have a big issue. Etc.
I do second the Elna. I know someone who loves the one she has, and they have some great features.
