I love my Accuquilt go! I also have the go me! the 2 1/2" die is one of the most used IMHO. Many rely on the cubes but I do not have any cubes. I just counted today I have 42 dies and one more on the way. Many of the BOB (block on board) dies can be used to make other designs. The 5" square is a good one to have around and the 4" (finished) HST are both very usable for a lot of quilting projects. I have a couple of triangles and 2 different size quarter square triangles. Always check that the finished size is what you are looking for. I hope this helps you a little.
