I wish you the best of luck curtailing your die shopping after buying an electronic cutter!
I justified buying my first electronic cutter by saying I wouldn't need to buy any more dies and/or punches.
Three (different) electronic cutters and hundreds of dies & punches later, I am forced to admit that the whole cutting of paper thing is an addiction. I will never stop buying dies & punches -- and I still buy manual machines, too. My Big Shot Pro and AccuCut GrandMark were purchased when I already owned awesome electronic cutters.
I love dies. They cut just about anything I need to craft with. And there's something about that always-perfect, slightly turned down cut edge. *sigh*
