They have dies on sale for 40% off several times a year. I know you want to just jump right in, but I would get the ones you need this first go around. I would also look at dies that work well together, such as the 2 1/2" strip and the 2 1/2" triangles. They also sell bundles for finished 8, 10 and 12" blocks with generic shapes that can be used for many different blocks. Instead of some 'want' dies, I would purchase the accessories first. You will need the extended tray for using the long strip dies:

you will also need the extended cutting plastic.
I would also invest in the larger GO! adaptor

Although the go dies cut fewer layers they are less expensive and might be a better choice for those 'want it' dies that will get less use.
