I have a Brother Nouvelle 1500s, the same machine as nygal pictured. Of the six machines I own, it is by far my favorite. It is an absolute workhorse. On my machine, the pin for the pin feed is removable. My machine came with a 1/4" foot and has markings on the plate for 1/4", 1/2", and 5/8" seam allowances. I've used paper-sided bobbins in this machine with success. I've also purchased metal bobbins in bulk from a friend who runs a quilting supply business out of her home, they are the basic L bobbins you can purchase anywhere.
For $150, you got a great deal!
