Macro Attachment for a 72mm filter size (18-200mm lens)

[Philby_Walsh]

I was about to buy the raynox dcr 150 macro attachment for use with my Nikkor 18-200mm lens (and D90 body) but noticed that the filter size of the lens is 72mm but the raynox dcr 150 is only suitable for 52mm to 67mm filter size.

Is there any way around this?

If not then any recommendation on a suitable alternative macro attachment would be most welcome.
