I think it would be fine for piecing. Area under the arm is small for machine quilting, but that is true of most domestic machines. For $100 I would be very tempted! Here is a link to the reviews of it on Amazon:

Edit: When reading the reviews, be sure to also read the comments on the reviews. I have found both the reviews and the comments associated with them very useful in evaluating purchases.
