Love the "Amish" quilts
If you really would like to have an Amish quilt, why not make one yourself? There are lots of books and patterns you can use. You don't have to be Amish to create a beautiful quilt, and I think the investment potential would be about the same. Plus it would have more meaning to future generations of your family because it was created by your own loving hands.. Just the way I think and for what my opinion might be worth to you...
