Decide if you want the 6", 8", 10" or 12" boxed dies in a book form. I bought the 8" and I usually make a 12" block but I have not used them enough to know what I really want. Some new and used dies are for sale on ebay and you can trade with or use friends' dies also. I have the Go Big and I am glad I purchased that one. I had both shoulders operated and right now have lots of pain. Pills every day. It's tough getting old.
