I am considering getting some PowerBlock Elite dumbbells. I'm curious if anyone has PowerBlocks how you like them. Would you buy them again or would you get something different? I have considered the Ironmaster adjustable dumbbells but they are more expensive than the PowerBlocks and look like they take a lot longer to change weights. Ihey look like they would take nearly as long to change as a standard dumbbell bar and plates with spin on collars. I really like the StairMaster TwistLock dumbbells but they only go up to 50 lbs. so they aren't an option. The only two real options I'm aware of are PowerBlocks or the Ironmaster's. Is anyone aware of any other options out there that go heavier than 50 lbs?
