Where can I get a decent wirebrush wheel for a bench grinder?

Just got myself a replacement bench grinder, Elu made in about 1988, nice solid tool, just hums and is so well-balanced it takes half-an-hour (well not exactly) to come to a halt after it's switched off.

But I need one wheel to be a wire brush, rather than a grinding stone. So I got one off ebay and boy did that make things rattle! It was so out of true the poor machine nearly unbolted itself from the bench. That wheel went back where it came from.

Can anyone recommend a supplier of a 6" brush wheel that's actually circular?
