I just attended a program at our LQS called there’s a die for that. The presenter said the Hunter Star and 2 1/2 strip cutter are the most popular. He also said if he had it to do over, the first die he would buy is the 6” cube and then the companion sets for it. That shop matches any ACQ online offer. I would rather give the LQS my business whenever I can.
I must warn you.... collecting dies is habit forming.
