This is the way I think as well. Don't overdo it. As someone, wiser than me, said: "Good enough" is not nearly as wonderful a thing as "perfect", but it's good enough.
I actually used Mainstage (and loved it) up until one particular, high profile and high paying, gig where the whole setup decided to fail on me in the middle of the show. All fine again after a reboot, but I still feel the pain in my stomach. Now I'm all HW.
