where can I get a skipping rope with ball bearings?

[Rosieglow]

The only one I've found was from a pound shop and although it says it's got ball bearings it doesn't seem to make the rope go round any smoother.

Any ideas where I can get a good one?

here?

here?

or here

Thanks, the wooden ones look like the one I've got which doesn't work properly. Perhaps I've just got a duff one.

I've seen the leather ones too - I think they're used by boxers?- thought they might be too long for a 5yo (sorry - didn't say I wanted a kids one!).

I've seen some really cute painted ones (fairies etc) on some sites but don't know if the rope's just knotted in.

Perhaps I'm just being too fussy....
