For quilting you need a straight stitch and sometimes a zigzag is nice. The other decorative stitches will likely not be used.
In looking at a picture of the machine, the throat space looks tiny so stuffing a quilt through it to machine quilt would likely be frustrating. The measurement that counts is distance on the right from needle to machine - not the distance that the table affords you to the left of the needle.
I agree - if you can test drive multiple machines, you will likely find something that works for you.
