Re: How do you feel about macro extension tubes?
The filters close correct things optically where as an extension tube actually puts the lens further away, which allows closer focusing (though you lose infinity focusing with an extension tube on). The one link you posted is for generic extension tubes an an adaptor to make them work with the Nikon camera and lenses.
As for a real macro lens as mentioned in the other threads...dunno. I'd like to get a vivitar series 1 90mm f/2.5 macro lens some day, because it could be useful to have something that focuses down to 1:1...though I doubt I would ever focus that close. There are a couple of 50mm macro lenses out there that I am interested in, even though they only focus to 1:2 and aren't "true" macro lenses.
For me I like doing close up portraits, and sometimes to get small details, like just a person's eye and the area immediately sorrounding it you need something like 1:2...and with a 50mm lens I would have the camera pratically in their face, which is akward, so a 90mm macro would give a much better working distance.
