If you are going to do a lot of macro work then I would definately go for a macro lens. (And then perhaps a focussing rail to put on your tripod also - that way you can set the desired magnification on the lens and move the whole camera back and forth to get the plane of focus where you want it).
If it's only going to be an occasional thing, either tubes to shorten the minimum focus distance on an existing lens, or close-up filters, might be acceptable (and a lot cheaper!)
I used filters briefly before opting for a dedictated lens, initally the sigma 105mm, but I now use the tamron 180mm to get a better distance for insects etc.
