Here's the link to the place I bought mine
http://sewingmates.com/index.asp. I bought the smallest one for $36. I like it and use it most of the time. There are times that the quilt will kind of hang up on the corner and moves it. I also made myself a "table"
http://sewingmates.com/index.asp, which I use in addition to the acrylic one, I wedge it in between the boxes. I already had the acrylic one when I discovered the thread for the home-made one. I couldn't get the right size foam boards, so I used boxes (free from post office).
