I buy mostly from Accuquilt website. They have good sales during the year and an easy return policy. I have about 65 dies. I have the Go and Go Big. Both are great machines. I rarely have to use my rotary cutter to cut quilt block pieces. I like the BOB dies the best (Block on Board). One pass and four to six blocks are perfectly cut. I have all the strip and geometric dies I need to make most any quilt I want.
