I have several students who are always looking for a new sewing machine and yes, I still sell a few sewing machine models for Singer.
You should be able buy a very nice Singer sewing and embroidery machine for under $1200.00. The Singer Futura XL580 is what I now use for everything and I love the machine for all kinds of sewing and embroidery. Must have features for a sewing machine include a front drop in bobbin, needle up and down, electronic speed control, easy threading, an easy buttonhole and lots of decorative stitches are also pluses. A custom bed extension can be purchased for any machine and is nice to have. The ease of electronic stitch selection is a must and good lighting helps a lot. The machine will last for many years and is a major life investment.
Here are links to Singer machines and video that show the operation and features of several sewing machines.
I carry a Singer Legacy line of sewing and embroidery machines. The nice thing about Singer is the on-line video instruction that you can watch to learn what your machine can do. Please click on the video links if you are interested. I have the sewing machine version Singer C440. and the sewing and embroidery version Singer SE300
I have recently added the Used Singer Studio embroidery only S10
