The typical price for a 20 kgs cast iron kettle bell is £50-70. What's involved in making one?
Iron only seems to fetch about 10p per kg at the scrappy.

Concrete ones are much cheaper to buy than cast iron, but the density of the material is different, and concrete ones are much bulkier. The advantage, of course, is you don't need an iron foundry to DIY one. :)

You could always use mercury rather than concrete.<g>

Lead has a density 20% less than mercury.
Tungsten seems a better bet! A bit less toxic too and on par with the density of gold.

Once at school we had a bottle with about a pint of mercury in it.
I tried to pick it up.
My hand just slid off the top. Most odd feeling.

Sorry, ignore units and replace with SG.

I'm not sure that I would trust his method for attaching the handle - I can see it pulling out of the Postcrete when the bell is in full flight.

Cheaper; if you're a government which already has some.

The bottom of the Instructables page, right hand tile, shows a handle modification, with rope and security pins. I don't think much of the rope, but the security pins would probably help. And the position of the security pins is good, as the stress will be distributed better by the handle, further up near the top.
You still have to decide what to make the security pins out of, for corrosion resistance.
