Which Power Block weight set to get?

I'm finally realizing I've outgrown my dumb bell set and it's time to upgrade to the Power Blocks! I'm wondering for you ladies out there that have them, do you have the Sport set or the Elite? It seems like the Sport should be enough for the foreseeable future at 24 lbs., plus I like that those go in 3 lb. increments instead of 5. Just wondering what everyone else has and recommends :)
