I have the Go manual and Go big. I use both. The mats are consumable so you will use a lot of those but mine have lasted through many cuts. I've only had to replace one die, the 8" rag die, because I wore it out making hundreds of rag squares for a guild community project. I went through several mat then too. For regular use I haven't had to replace any of the dies. DH replaced the bearings in my Go crank and it's about 12 years old. I bought one of the first ones available. You'll find pros and cons with any fabric die cut machine. Just pick one and not fret about what you should have bought. That will take the fun out of what you do have.
