Fast can be GOOD! I have a Singer 95-80, which is dated from the 1930s. I've had it since 1986 and it has been in for repairs exactly once. The savings on annual tune-ups has paid for the machine five times over.
I liked it so much that I bought an earlier "clone" of it, a 95-30. Kind of nice to have two of a kind, because when the timing on my second machine was off, I partially disassembled the first to get a good look at how it was supposed to be, and was able to fix it. The manuals are available online through the Smithsonian archives.
Lori is right, that you want the machine WITH the table, and the motor is generally attached to the table so those come as a unit.
You will LOVE the flat smooth sewing surface of the table. And also the knee-lift lever, which leaves both hands free to manipulate the fabric.
BTW my machine only does straight stitch and only goes forward, but that's the majority of the sewing you do on a quilt anyway.
