How Many LEGO Death Stars Is Too Many?

Exactly a year ago, I posted a photo of my three LEGO Death Stars. Today, I can share a photo of the fourth. How can I justify all of these? Well, according to Wookieepedia, there were at least 4 death stars in existence at one point or another.

So maybe the answer of how many LEGO Death Stars is too many is: one more than I have at the moment.
