I have to confess I know little about the Nikon cameras, but expect that their metering is pretty accurate, a hand held spot meter probably isn’t exceptionally more accurate and they can be expensive, maybe not worth a great outlay unless you are really going to get a lot of use from it, at the end of the day all it does is set the aperture and shutter speed.

If all else fails there is always the sunny sixteen calculation lol

 

The Canon spot is 2.4% and multi spot on their pro DSLR's and 9% partial on the 20D and the like, with a 3.5% on the 30D and 5D, I suspect that the larger spot is one way they keep their prices competitive.

 

Kind of off topic a bit now, so better just bid you good luck with your photography ventures.
