I have several machines and the one I take to classes is a Brother rx 7700 (I think the letters are right-The number is for sure) It is a fantastic light weight machine. It is about $170. from Costco and if you are going to start a young quilter, it has every foot you need for quilting (including the walking foot), applique, and general sewing and makes a button hole the size your button is with a special foot. It isn't as cheap as the Ikea but a great inexpensive machine.
