I know a number of people have spoken pretty highly about power blocks. Does anyone have any experience with or knowledge about the quick change dumbbells made by ironmaster? The reason I ask is that for a 125 lb set, the power blocks look like they will run about $942, while for a 120 lb set, the ironmaster set looks like it will be about $658. I am just curious whether there is $300 worth of difference between the two.
Thanks in advance.
