I still use my Versa Bell 25lbs I picked up from Target quite a bit. They go from 5lbs to 25lbs but it's not a quick change. I wound up going with an adjustable plate weight set for higher weights because I was worried I would spend several hundred dollars on another set of non-plate adjustable weights only to outgrow them in a couple of months. I think I will even outgrown the new set in a couple of month but since they are plates, all I have to do is buy higher plate weights. By the way, it was an ex-military friend of mine who lifts 6 days a week that advised me to go with the plate weights. I think he was right about it even though it does take some planning before the workout since it takes a bit to change out the plate weights. HTH!
