I already have a Singer embroidery machine, the Futura SES 2000 All-In-One, which I purchased on HSN back in
2009. Love, love, love it. It sews, cross-stitches, auto-punch, photo-stitch, embroiders and supposedly serger feature as well although I have not used that feature. I don't sew on it much either simply because you can't use the start/stop button but a foot pedal for sewing. Anyway I mainly had selected it to do all the other stuff such as embroidery, photo-stitching and such.
I've been eyeing the Singer Professional 5 Serger for several months now and probably will end up getting that in a few months. Been waiting for price to come down on it and although it has quite a bit I'm still looking to save even more dollars. I did research on this one as well and compared it with other Sergers and it seems to be the fit for me. I also want to make sure that I just can't live without it before I buy it.
