It's all in the eyes of the beholder. I'm a fan of toppers that look cool, and I pass on the ones that I don't dig. I'm not "for" or "against" them. It really depends...
Prime example: I bought the Governor's Fish Tank for my TWD. Looks cool as hell IMO. I love it. On the other hand, I passed on the Ghostbusters topper, because it's $500 and looks cheap to me - but again - to each their own.
