How many antiques auction houses can one city support?

Martin and I don't often disagree but we've got a bit of a friendly bet going on whether or not Sydney needs one more auction house in the antiques market mix.

It's Martin's contention that the city needs a medium sized antiques auction with a yen for real quality, somewhere between the top tier auctions and, oh, I don't know, Ma and Pa Kettle's local livestock sale.

Martin's tipping Theodore Bruce, the long established South Australian auctioneers who are the new kids on the antiques block in Sydney.  What we've seen so far, we like.
