If you are the type of sewist that is happy making the same blocks and the same size blocks over and over again this may be a good option for you.
You haven't kept up with the dies available. There are Qube sets that have dies to make 4" 5" 6" 8" 9" 10" 12" and 16" block sizes.
There is a new electric cutter called Go Bolt that is portable, will be available in Oct.
