I know there are many members that have absolutely no problems with using a normal foot to create their scant or regular quarter inch seams...I just always had the problem you are describing.
My solution was the quarter inch foot as many have listed above with the right guide to help keep my seams accurate and have never looked back. Since I use my Pfaff my IDT (walking foot) it is always engaged when piecing my fabrics so both top and bottom move together at the same time. I also use it for straight line quilting for exactly the same reason. Course with FMQ you don't use the IDT (walking foot) but have found that it really isn't necessary because you quilt from the middle out and that takes care of not having bunching in your quilt back.
