I have an older SE 350 combo..... sewing/machine emb.
I LOVE it... the embroidery is easy to set up and works smoothly. My 350 only has up to a 4x4 hoop... I would love to have a minimum 5x7 hoop... that is my only complaint, towards the emb part. As for quilting, The harp is so small. It makes things difficult and I am only able to quilt lap size. I am visually impaired , so I have an added light.. but that might just be me.
My machine gets used daily.... emb several times a month. I've never had a problem or a malfunction that required a visit to the Machine dr.
good luck
