I used to feel this way, until I get balls and they are not the "greatest ball ever made" and end up taking up space and a waste of money.
Lately, my ball purchases has been limited to maybe one or two a year. My last purchase was a Snap Lock a few months ago, and prior to that was a Joyride last year.
I think my arsenal is pretty solid, so unless something cracks in half, I just enjoy the hype but don't bite.
