I figure when the mats wear out I will have cut several quilts with a single die. I am pretty new to my Accuquilt Go! I am finding it to to work much better than my hands can ever do. Costly but worth it. I strongly suggest you look on Marketplace to see what is available used. I also understand that the Accuquilt Go Big! is prone to electrical problems. Best bought from Accuquilt because under many circumstances it is cover by warranty. I purchased different size mats especially to have one for the longer dies. I can use the 5" mat if necessary and back up a bit and run it through to complete a single pass for a size I may not have. Several mats came with my machine that I bought used. I got 20 dies and mats and the machine for $60. Just because it says $150 doesn't mean the seller won't accept far less. That is what I did. I know this is my second comment but I have learned more since I commented last time.
