For simple piecing, my recomendation is to go to a dealer and look at their used trade ins for something like a phaff, elna, I have an elna I bought before my second child was born - she is 42 and it is my favorite machine for piecing.
The electronic ones take an extra stitch when you try to get them to stop. I don't like that. I have 3 other machines. That are newer. Take the machines for a test drive. If you can get a good satin stitch and good straight stitch you got it made. I also have a Viking 1100 that I use for sewing leather. A D-1 for embroidery work and everyday stuff but my best piecing machine is the elna. A good used machine is better than a plastic new machine, in my opinion.
