My Go is over six years old, one of the first ones made. I use it for 90% of my quilt cutting. I have most of the dies. I use the 2 1/2" strip die a lot. The large rag die, large tumbler, and log cabin dies are some of my favorites. I'd buy another one if it broke.
If you want a machine for quilting I'd buy the Brother 1500 or Juki. Both are excellent for piecing too.
