Adjustable Weight Dumbbells

Does anyone know where I can find the type of dumbells that you can slide 10 lb plates on and off of, but that hold more than 60 lbs total? The one’s I have now only go up to 60 lbs, and my searches yielded pages for the “PowerBlock”.

walmart has them …

you can also make your own from with pipes 18" or 24" galvanized iron pipe and can well hold uo to 200lbs
