I agree...
Just wait for some sales and get the normal acrylic rulers...
Cutting and piecing precisely is the key to a beautiful quilt...
Perhaps there are some quilters that would love to "donate" to you their older rulers so they can shop for new...
I personally only have 2 or 3 that I regularly use and bought years ago. Don't need any of the fancy ones...
I think all 3 cost me about 50bucks without a sale.
