There are many good arguments against the British royalty -- cost is not one of them. Were they a private family with private holdings, the people of the UK would pay more taxes than they do now.
The only way you can argue that abolishing the monarchy would save money is if you argue that they should be stripped from their private property. But if you start such land redistribution, just where should you end? Most of the land in the UK is held by aristocrats. And the US is not much better -- in the wealthy areas in the east, most of the land was originally acquired by means that would be less than reputable today.
You could kind of argue that all of the land in the US was acquired by less than reputable means. :P
Death duties? Capital gains tax?
Actually I have no strong feelings either way and tend to view the monarchy as part of the tourism industry.

Thanks guys!
If there was nobody living at Buckingham Palace, far fewer people would go see it.
The Dutch royal family moved from Amsterdam to The Hague, still, their old palace is still a big tourist attraction.
better than living in a 40c desert.
