Just wanted to put my two cents worth in even though I'm way behind the rest of you. I have the 12" X 12" and I love it. In fact I've been using it a lot the last few days. I'm trying to get a lot of large scraps cut into strips for a strip quilt after I get settled into my new house. I think right at first that's the only type of quilt I'll be making. Too much other stuff to be doing.
I would like to have the 12"X18" but am waiting for a 50% off coupon. 8-)
