I checked out Yahoo groups and there are a couple for the Singer Futura Quintet. However, there aren't a lot of members and neither group has been active for a year. This indicates to me it is not a popular machine. Usually there is a good reason why a sewing machine model is not popular.
I would also suggest the PE-770 for embroidery. With a separate embroidery machine you can be doing other things (such as piecing on your sewing machine) while the embroidery is sewing out. The sew-outs can take some time. The hoop size of the PE-770 is smaller than that of the Singer, but you can still do a lot with that size hoop.
