Save it. Money can be a powerful means to make more money, but clearly you didn't need 60k to make another 60k so there's more to it than just that. Where do YOU want to be next? What's your next product or market? What's your timeline?
If you have a reason to spend that money, and it better be a damn good one, , then spend it. None of this "to be a success I need a really bitchin desktop with 18 monitors and a new Joop Suit."
