Best sewing machine for me?

i want one that will last me forever without breaking allot and that would allow me to sew things i could sell online. I have a simple singer now and hate it, i want an automatic threader so bad!!!! I was looking at brother but i hear janome is good also. I might quilt but i will use thick fabrics anyhow, want a machine that could embroider somewhat and how about sergers! i have no idea about those should i buy one? I will also be buying camera that will last me forever also so I don't want a crazy pfaff or anything..any ideas for me?
